Subject: P2P/ v1.0 to P2P v1.0.x Interconnectivity over TCP/IP
 
TCP/IP address within the same workstation, in P2P/2 v1.0.1, is 1376 and
5001 for P2P/2 v1.0. For example to convert address books from v1.0 to
v1.0.1, use 'Export' from the P2P v1.0.1 Address Book utility and then edit
the exported file (now in ASCII), and change 5001 to 1376. Next this should
be imported.

Subject:Installation "Serious Disk Error"
 
if Serious Disk Error msg is popped out during installation of P2P/W, then
decrease the size of virtual memory(swapper file).
 
===============================================================================
 
Subject:Async Reliability Problem
 
If P2P/2 v1.0 over Async used for a long time it may crash the system. To
get over this, specify a large swapper file (20MB). P2P v1.0.1 handles this
thru better memory management.

Subject:ActionMedia without the Capture card
 
The effect of using AMII card without Capture card (the card that plugs on
to AMII), is that the Dual View will be greyed out. In addition only local
software emulation or remote software emulation/Video can be viewed at any
one time.
 
===============================================================================
 
Subject:ISDN - SCII card
 
SCii ISDN needs subscriber number. Note that SCII configurator doesn't give an
error and the NDIS MAC drivers that P2P uses, need this information.

Subject:ISDN - SCII Card
 
If inadvertently  made a voice call from Address Book and also had a
Data app checked, then the voice call will go thru, however the data call
starts but will fail, as expected.

Subject:ISDN - SCII card
 
To remove SCii mac drivers from WfWGs Control Panel-Adapters listing, delete
\windows\system\oem0.inf file. Don't mistake INF with IBM's NIF file, though
they are similar.

Subject:ISDN - SCII Data call Limitations
 
SCii cannot handle 2 data calls, however this is possible with the IBM ISDN
card. But you can have a data and a voice call with SCii. IBM ISDN doesn't
support voice explicitly.

Subject: P2P Clip & Windows for Workgroups clip/DDE Interoperability
 
   -  P2P's Clip provides for sharing of clipboard/DDE between communicating
      workstations; Microsoft's Windows For Workgroups offers the same via
      a different user model.
 
   -  This note confirms that P2P's Clip will happily co-exist with W4W,
      and, furthermore, will interoperate as follows -
 
   -  Suppose we have 3 PCs, A, B & C; A & B are running W4W and
      have shared a page in the Clipbook such that clipboard and DDE
      operations are shared between them; B nows calls C using P2P and
      shares Clip onto the call. If A and C each run an application such
      as Excel, Lotus, or whatever, then if A copies cells to the clipboard,
      C can Paste (clipboard) and/or Paste Link (DDE) and it will work.
      (The reverse direction and any other combinations of machines will
      also work).
 
   -  Note also that, in the scenario above, C can be running either OS/2
      or Windows (the same restrictions would apply as in the general case
      of two machines of differing operating systems for P2P Clip).

Subject:P2P Clip & NEOS Peer LAN clip/DDE Interoperability
 
   -  P2P's Clip provides for sharing of clipboard/DDE between communicating
      workstations; IBM's NEOS Peer LAN offers the same via
      a different user model.
 
   -  This note confirms that P2P's Clip will happily co-exist with Peer
      LAN, and, furthermore, will interoperate as follows -
 
   -  Suppose we have 3 PCs, A, B & C; A & B are running Peer LAN;
      B now calls C using P2P and shares Clip onto the call. If A and C
      each run an application such as Excel, Lotus, or whatever, then if
      A copies cells to the clipboard, B then uses Peer LAN "Network
      Clip/DDE" to "Copy" the clipboard and "Get" the data from A; then
      C can Paste (clipboard) and/or Paste Link (DDE) and it will work.
      (The reverse direction and any other combinations of machines will
      also work).
 
   -  Note also that, in the scenario above, C can be running either OS/2
      or Windows (the same restrictions would apply as in the general case
      of two machines of differing operating systems for P2P Clip).

Subject: P2P Clip & Windows for Workgroups clip/DDE Interoperability
 
   - A minor snag has been uncovered with the way we got Clip to happily
     coexist with W4W. These notes explain how W4W works, what we did
     to cope with it, and why there's a small snagette. In the following
     remember that "clipbook" is W4W's clipboard sharing utility.
 
   - Suppose machines B and C are running W4W, and C and D are running
     P2P with Clip.
 
   - D copies something to the clipboard; Clip sends the list of clipboard
     formats to C, where Clip copies them to the clipboard; W4W clipbook
     notices this, and copies all the formats and the data (so Clip fetches
     all the data across which was delayed up to that point and renders it)
     onto its shared page for B; THEN (rot its socks) it ADDS a private format
     called "Clipbook Preview" to the clipboard on C WITHOUT emptying it
     first;
     Clip gets a message saying the clipboard has been updated, reads the
     contents and sends it all back to D (whence it originally came).
 
  -  That was considered undesirable, so what we did was: when the message
     arrives to say "clipboard updated" we check to see if the format
     Clipbook Preview exists on the clipboard and if it does we ignore
     the update (so it's not "bounced back" to D).
 
  -  Then, however, suppose B updates it clipboard, W4W copies it to
     C which gets its clipboard emptied and filled with new formats and
     data, *including* "Clipbook Preview"; now Clip gets the update
     message but ignores it because of the Clipbook Preview format.
 
  -  To fix that, we used the fact that whenever Clip fills a clipboard
     it adds its own format (for Windows "P2P/W-CLIP") to the others.
     So, now when Clip gets a "clipboard update" message, it checks to
     see if the formats include Clipbook Preview *AND* P2P/W-CLIP, in
     which case the message is ignored (because W4W must have added its
     format without emptying, which it only does when it is *reading*
     the clipboard to copy to its shared page). When B's page gets copied
     to C, W4W empties the clipboard first, hence P2P/s format is
     missing, so we then correctly pick up the message and send off the
     contents.
 
  -  Snagette: Suppose we now add machine A which is connected by P2P
     and Clip to B. (Remember B is sharing clipbook via W4W with C, C
     is connected by P2P and Clip to D). Still following? Now A copies
     some stuff to the clipboard; Clip sends it to B, adding its own
     format of P2P/W-CLIP to the others (hear it coming..?..); B copies
     it to C via W4W which adds its own format of Clipbook Preview;
     Clip on C gets the "clipboard updated" message, but IGNORES it
     because both formats are present.
 
  -  We have decided to live with the snagette. Why? Because -
 
     1  it's a pretty unlikely scenario for anyone to hit.
     2  since B and C are both running P2P, they could P2P call each other
        over the LAN (they must have a LAN because they are connected
        by W4W) making a 4 way P2P & Clip call, and do their clipboard
        sharing that way; any shared page on the clipbook between B and
        C should be unshared before doing it; then everything will be
        fine. i.e. there is a work-around.

Subject: Run-time DLLs for IBMC, and CommonView
 
    Products which are sold, and include run-time DLLs from other products, may
    encounter problems. For example, suppose P2P includes DLLs which are
    part of the Glockenspiel CommonView product; those DLLs are installed on
    the user's machine in his libpath and are used by P2P.  Now suppose that
    the user buys another product which includes the same Glockenspiel DLLs,
    these new ones are installed on the libpath, maybe overwriting the P2P
    ones, or maybe being put on the libpath before P2P's. Now when P2P runs
    it will use the new ones. This may cause problems. Further, suppose that
    the P2P ones were advanced ones with new features, and the second product
    the user installed had older versions lacking the new features. Now P2P
    will not run because the features are missing; worse, the P2P ones may have
    been overwritten and P2P has to be re-installed; then the P2P ones may not
    work with the user's second product (worst case!) in which case the user
    cannot use both products on his machine at the same time.
 
    P2P
    ---
 
     There are two potential areas where we could hit this problem -
 
    IBMC
    ----
 
    Ibm C has a runtime DLL called CRTLIB.DLL.  P2P does NOT use this, instead
    we have a system (designed by Andy Key together with DCL) in which all
    the ibmc run-time routines are kept in our own-named DLPCRT.DLL which thus
    uniquely named will not clash with any of the user's CRTLIB.DLLs.
    This was done because many applications are written in C (and the
    particularly name CRTLIB is common to many C compilers other than IBM's)
    and a clash was considered quite likely.
 
    CommonView
    ----------
 
     Glockenspiel's CommonView, as used by P2P, needs 4 DLLs, called -
 
      GLFS31DP.DLL
      GLCV31DP.DLL
      GLSH31DP.DLL
      GLTD31DP.DLL
 
    P2P DOES use these, they are installed by the Install program and exist
    in the C:\P2P directory along with all the other EXEs and DLLs.
    If the user installs another product which uses the same DLLs, the problems
    described above could occur.
    It was considered unlikely that a user would install another product
    written using CommonView and hit a clash problem. P2P uses CommonView
    3.0 Beta 3 DLLs which are very recent.

Subject:TCP/IP checklist for P2P/2 v1.0 only
 
    - Go to TCP/IP Config panel (from Call Mngr select View - Configuration
      and then TCP/IP) and check "Use Slip" and "Enable" are ticked. Afterwards
      click on Defaults. Also check the internet address is correct.
    - Check that the following statements in CONFIG.SYS.
      DEVICE=C:\TCPIP\BIN\INET.SYS    ;assuming that TCPIP is on C: drive
      DEVICE=C:\TCPIP\BIN\IFNDIS
      SET SLIP.COM=COM1     ;com1 is the default
    - Check that SETUP.CMD in TCPIP\BIN directory has the following line:
      ifconfig lo 127.0.0.1
      This is described in P2P/2 Using Guide v1.0 in Appendix A pp4.
    - Make user that Slip is enabled within the TCPIP itself.
    - Initially just let P2P to use TCPIP and not anything else for test
      purposes.

Subject:Address Book Format
 
   P2P Address Book format (and content) are not consistent with any other
   product like:
   Time and Place/2,
   Lotus Notes, (using Vendor Independent Messaging interface)
   WPSHARE93 style (as on OS2TOOLS),
   VM Names file style.
   Address Book Synchronization/2
   Lotus cc:Mail (VIM)
 
  In P2P defence, the address book interface was coded to allow for using
  various formats. P2P can accept interface DLLs (called Database Support
  Modules) which allow it to access other address book formats.
  The problem is not design but the fact that no other DSMs have been
  written.

Subject: Information on VideoLabs FlexCam Camera
 
   From the FlexCam box...
   -----------------------
   FlexCam Desktop Color Video & Sound is a high resolution,
   integrated color camera and microphone. FlexCam's video output is
   industry standard NTSC or PAL. And Flexcam's low noise, directional
   microphones deliver top-quality, line-level stereo audio. FlexCam's
   60 degree swivel "head" and 18" flexible gooseneck offer precise
   camera positioning. And the adjustable focus lens gives you razor sharp,
   real-time color video from a quarter-inch to infinity.
 
   Our experiences...
   ------------------
   We used our Flexcam for the first time yesterday and we were amazed!
   We've replaced our bulky camcord that we use with P2P with the FlexCam
   and we were able to have 5 of us in the picture at all times. What was
   really amazing is the level of detail you can get when you point the
   Flexcam down onto a coin or at a large open room. We really were
   amazed that for 500 we could get such a high quality camera. We haven't
   used the mics yet, but if they're even half the quality of the video
   image, they'll be better than anything we have to date. We'll be using
   the FlexCam for video conferencing or for showing foils, etc. when we
   can't get the images online.

Subject:Poor Still Pictures
 
   If you have problem with the quality of still pictures then consider the
   followings:
    - Ensure that the 'Enhanced Still' option ticked.
    - When you are happy with the image you have captured, select Save as
      and where you see the ComboBox, 'Save file as type:', select
      8 bit per pixel OS/2 bitmap. This means the image will show up better
      on the display.
      If you select 24 bit per pixel OS/2 bitmap, the package/app. that you
      use to display the image, should have the option to Halftone / Error
      Diffuse the image.

Subject: Cannot get the following applications to be mirrored to P2P Chalkboard
 
   App 1:Micrografix ABC Flowcharter
         This is a Windows app. and currently P2P cannot mirror
         full-screen WIN-OS2 applications.
 
   App 2:Lotus 123 for OS/2, Version 2.0
         When trired to mirror a Lotus spreadsheet into P2P chalkboard, doing s
         brings down Lotus with the following error message:  SYS3175 A
         program in this session encountered a problem and cannot continue.
         A program generated an access violation at 15e1e1e3.
         The solution is to add the following line to the CONFIG.SYS and reboot
                  SET P2P_MIRROR_BUTTON=OFF
         or
                  SET P2P_MIRROR_BUTTON=FLOAT
         For some reason, Lotus OS/2 apps all behave this way.
         This will prevent the chalkboard from trying to subclass the
         application frame to add the extra mirror icon and will cure the
         problem for both 123 and Freelance.

   we were using software video but this looked great once we figured out how

Subject:WACOM Tablet
 
   Installed P2P (selected WACOM TABLET) and as a result, could not

   The WACOM tablet driver *replaces* the existing mouse driver.
   To support multiple pointing devices, you need Pen PM.
   Other 'solutions' require undocumented/unsupported features in MOUSE.SYS.
   Try OS2TABLT FORUM...
   Or request the PenPM package? This will give all the required support.
   Look at PENPM_B FORUM for more details.
   Not only does this gives full TABLET support for OS/2 and can also use
   seamless Windows Apps.
   Also try:
         DEVICE=C:\OS2\MOUSE.SYS TYPE=IBMMOU* STYPE=TABMOU*

Subject:Modem Call Clearing
 
   The call clearing phase over Modems is rather longish sometime, even if
   the Call Mngr reports that there is no call active.
   The best indicator is to check whether OH (onhook) is active/lit, if so
   then the modem is ready for i/g + o/g calls.

Subject:16650 UARTS
 
   When high quality fast modems and high speed UARTS (16550A) used then
   use of P2P over modems is quite acceptable. Delays depend upon data
   far less than on P2P. P2P compresses that data before it is sent to the
   modem, all that is "missing" from P2P code is error correction but good
   quality modems will provide adequate error detection and correction.
   We recommend use of Modems with V42/V42bis.

Subject: Video Freeze
 
   If video freezes for sometime (eg:5 to 20 seconds) while drawing/pasting
   on the Chalkboard, this may be due to:
    - Slow 386 SX machines
    - Lack of memory
    - Bridges between PCs
    - Ethernet networks get heavily loaded when the usage gets above 30%.
    - Video data has lower priority within P2P wrt Talk, FT, Clip and Chalkbroad
      data. Therefore if for example chalkboard is used (eg:free hand drawing)
      then obviously this higher priority data is transferred wrt video data.
    - Set compression to None in the communication sub-system panel. This will
      improve the performance if software emulation is used.

Subject:DDE and Chalkboard Mirroring
 
   Is it possible to have DDE support and Chalkboard mirroring with an

   The answer is YES, provided that the app is windowable then P2P should
   mirror it to the chalkboard. With regard to DDE, if the app supports DDE
   then P2P DDE should also work.
   If both DDE and mirroring used at the same time, beware, the system

   been installed so that it can be minimised to a window then mirroring is
   possible.
   If Win-OS2 has been installed to run in full screen mode, it is still
   possible to mirror Windows apps but these should be run directly from OS2
   desktop rather than from within Win-OS2. This is done by using the
   program template.

Subject: P2P video size
 
Q1) What is the size and color capability of the captured video image?
    ===== I think that I read somewhere that the size is 128 x 120 x
         256 colors.  Can someone clarify this???
 
A1)  Here goes for a confusing answer ! The video is captured from AM-II
as 128x120 pixel frames in YUV9 format. At first glance, this appears
to suggest 512 colours but the card does fancy processing on the images
and gives you a resulting image that looks pretty much like a 16 or 24
bit per pixel image (IMHO).
 
  Video sent to other AM-II users is compressed using the RTV algorithm
then decompressed for display by the AM-II hardware in the receiving
machine. The situation here becomes rather complex, however, since the
displayed image does not look like 128x120 on your PM or Windows screen
due to the fact that the AM-II mixes its video plane with VGA or XGA
and that these 2 planes have different pixel sizes.
 
  Imagine 2 similarly sized sheets of squared paper with different square
sizes overlaying one another. The top sheet represents the PM desktop and
the bottom one the AM-II frame buffer. A block of squares drawn on the
bottom sheet shines through to the top sheet but occupies a different
number of squares at different coordinates from the top sheet viewer's
perspective. (Does this help any ? It's difficult to explain without
drawing a diagram. Call me on P2P if you are still confused).
 
  For a 128x120 (AM-II pixel) image, the perceived video image sizes (in
desktop pixels) are below. The 2 values for AM-II resolution give the
size of the whole "bottom sheet" depending upon whether or not you have
checked the "High resolution" box in the display controls dialog.
Remember that this "bottom sheet" represents the same physical screen
area as the PM desktop (the "top sheet").
 
PM desktop   AM-II res    AM-II res    Apparent image size (PM pixels)
              (high)        (low)           (high)      (low)
 
 640 x 480   512x480      256x240          160x120     320x240
 
1024 x 768   410x384      256x192          320x240     512x480
 
For example, with a VGA display showing AM-II video in low resolution
mode, the 128x120 AM-II pixel image looks to the user like 320x240
VGA pixels (ie quarter screen).
 
  If using software video, the captured images are all 128x120 and use
either 256 grey levels (if you select mono images) or 256 colours. These
images are displayed using PM (or Windows GDI) and appear either as
128x120 PM or Windows pixels on the screen or stretched to fit the
supplied video window.
 
Q2) Is it possible to zoom the chalkboard so that a complete image can
    be viewed
    ===== It has been my experience that the size of the image you see
         is less that the real image and is dependent upon the
         resolution of the display.  My 8514/VGA appears to show about
         25% of the total chalkboard capacity.  I can find no zoom
         feature.  What is the size of the chalkboard in pels?
A2)  There is no way of zooming in or out in the Chalkboard. In all cases,
the chalkboard contents are shown pixel for pixel on all connected
machines so if different resolutions are used on different machines
in the same call, people see different percentages of the chalkboard
area.
 
  The chalkboard scales dynamically as you use it so if you draw off the
edge of the currently defined area, the chalkboard size increases to
accommodate the new drawing. I'm not sure what the maximum size is but, on
version 1.0 at least, it was enormous ! (Tip - don't zero the scroll bars
on 1.0 and draw in the top left. Your machine is likely to page forever
trying to allocate memory for an enormous image. This is fixed on 1.0.1
as far as I can see).
 
  If you get lost on a large chalkboard, Ctrl-Home moves your viewing
position back to the centre and, if you are really desperate, someone
else using the "sync" control will retransmit the chalkboard contents to
you and move your viewing position to have the same centre as theirs.

Subject: Chalkboard Questions
 
Q1 - When you share a chalkboard to a call for the first time, do you transmit
     an empty Chalkboard, or simply some instructions is sent to the
     destination to launch a Chalkboard.
 
          - just sends instructions
 
Q2 - When C/Brd is partially updated, do you transmit whole of the c/brd or
     just the updated area.
 
          - just the updates
 
Q3 - What sort of display drivers would you suggest for the user to use for
     optimum picture sharpness and faster transfer of images thru C/Brd:
     OS/2 Display  drivers
 
     Tseng  "       "
     S3     "       "
     Cirrus "       "
 
          -         don't know.  Obviously there is a trade off between
                    picture quality (bits per pel) and transfer times.  The
                    more bits per pel the slower any updates are.

chalkboard:
 
SET P2P_PALETTE=ON
 
To disable this feature remove this line from CONFIG.SYS or enter at the

Subject:NETBIOS - Lack of Resources
 
  When a couple of people try to run Person To Person/2 off a LAN
  server, they get a message telling them that resources have run out
  Because of the large number of DLLs in P2P, each person running off the
  LAN
  places a load of about 25 file opens on the server.  As the standard LAN
  server configuration only permits 64 file opens, they soon run out.  Try
  increasing the number of file opens; a figure of 256 will let up to
  ten people access P2P, a couple of thousand will make the server logon
  limit the first barrier rather than the file open limit.
 
  Alternatively, get each user to install P2P for local use on their own
  disk and just make the site directory shareable.  Doing this makes P2P
  faster as well.

Subject:Jummy Video over LANs
 
  When I make a call that crosses a LAN bridge etc the video seems
  very jumpy and uneven.
  The solution is to do with frame rates. If the user is using a network with
  a slow link in it, for instance; imagine you have two users on separate
  LANS communicating over a slow bridge, then although you can set the P2P
  framerate as high as 15 frames per second, you will not necessarily get this.
  In fact what you will get is uneven video delivery. You might get a few frames
  quickly, followed by a wait of say a second. What I recommend the user do, is
  to estimate how many frames a second he is ACTUALLY getting on average, this
  can be done by counting how many he sees over say a minute, and reducing the
  framerate on P2P to this amount. At least then the video delivery will be
  even. An example is for ISDN; the ISDN maximum selectable framerate is
  about 2 frames a second but when you first install P2P, the default is about
  1 frame a second.

  Why is there no tool for drawing straight lines on the chalkboard?
  You can draw straight lines by drawing an unfilled box and making it

Subject:SYS1804 System Error Message
 
   When I try to start P2P I get the message:
   SYS1804: The system cannot find the file .
 
  This message may occur because P2P is not being executed from
  its own directory or because the ".;" has been removed from the
  libpath statement in config.sys.
 
===============================================================================
 
Subject: My ISDN calls seem to fail for no reason.
 
   This sort of thing can happen if you unplug the ISDN cable from the line.
   If a user running P2P is not in a call and for some reason tries unplugging
   then reinserting ISDN cables, it can cause problems if they then try
   to call someone. This is because the ISDN card may need reinitialising with
   the ISDN exchange. If they experience such problems, and calls are failing,
   they should restart P2P and try again.
   This problem occurs because we cannot detect when a cable has been removed,
   unless a call is in progress, in which case the call is dropped.

Subject:Unsmooth Video Window
 
  I have noticed that the video is less smooth when I overlap another
  window over the video window.
  If you partially obscure the video window, the video subsystem has to work
  much harder working out where not to display video.  To ensure smooth
  video, avoid partially obscuring the window.

Subject:Large Address/Phone Book
 
  I have a large phone book (more than 500 entries) and manipulating it is very
  slow.  Is there anything I can do?
  Yes; split your phone book into several logical elements, such as
  alphabetically or by department, taking care to keep the size of each element
  well below 500 items.

Subject:Calculation of ActionMedia Frame Rate
 
  How can I calculate the ActionMedia II video frame rate that will be
  achieved given a particular link bandwidth or, conversely, how can I
  calculate the bandwidth used by a given AM-II video rate ?
  In general, with low quality video selected in AM-II VSM config panel:
 
                       1 fps = approx 3.5KBps = 28Kbps
 
    This scales linearly with frame rate, so:
 
              bandwidth = approximately (28 * frame_rate) Kbps
 
    Note that this is for each video stream so the total bandwidth used will
    be twice this if, for example, 2 users are viewing each other.
 
    Using the above figures, the following values drop out:
 
    Max rate over ISDN  (64Kbps full duplex channels)    = approx 2.3fps
                  Async (9600 baud = 960 bytes per sec.) = approx 0.25fps
 
    Beware of bridged LANs or TCP/IP connections. In multi-hop communications
    situations, the maximum frame rate is governed by the minimum bandwidth
    link. Just because you are pumping out TCP/IP onto a 16Mbps Token Ring,
    there is no guarantee that one of the hops to the final destination is
    not being carried at 110 baud over a piece of wet string !
 
    Over a normal LAN, video rates on 486 machines are limited to 15fps (if
    you have an NTSC camera) or 12.5 fps (PAL camera). Rates will drop back
    if running on a 386 machine (8fps is reasonable) or in a multiway call
    (where the frame rate depends upon many factors involving the machines
    in the call and the network topology).
 
    If the high quality option is selected in AM-II configuration, then the
    frame size increases to around 5.5KB. The remaining calculations are left
    as an exercise to the reader !

Subject: Problems with starting the chalkboard
 
I just installed P2P/2 v1.02 on my mod 95. I'm a
new user of P2P, and I'm noticing a problem when I try to start the
chalkboard.  Even though I have 24M of RAM and the hard drive where
my SWAPPER file lives has 90M+ of free space, it seems like I still
have to shut down practically every application that's open before
starting the chalkboard in order for the chalkboard to start up
successfully.  In the cases where I don't, a couple of different
things happen: after hearing a beep, I have to hit CNTRL-ESC
repeatedly until I get a popup that says that Person to Person
is not responding to system requests.  After selecting ENTER to
end it, I then see the popup that indicates that there were
insufficient system resources (memory?) and to shut down some
applications and try again.  After clicking on OK, one of two things
happen: either my desktop gets blown away and then comes back (the
good case), or my desktop gets all hosed up (PM windows garbled,
unable to access task list, etc.), and I have to reboot (obviously,
the bad case).
I'm using an Image Adapter/A with a 6091 monitor.
 
 
Using an IA/A makes a huge difference ! In their wisdom, the writers of
the original IA/A OS/2 drivers set a very low limit on the number of
bitmap handles that the driver could cope with (I can be nasty since all
these guys have now left IBM :-) ). In most cases, this limit doesn't
pose a problem but the person who wrote the chalkboard decided to use
up 49 (or was it 52 ?) bitmap handles, immediately blowing the IA/A
driver out of the water.
 
Although I can't be sure that this will work, you may like to try the
latest version of 2.0 IA/A display driver.
 
Well, I've got the 32-bit device driver installed, and P2P works *much*
better.  I kept all of my normal applications active, and had no problems
at all starting up the chalkboard.

Subject: What is H.320 and H.260 standard?
 
H.320 is a hardware standard from the CCITT (now ITU or something ?)
which defines audio/video/data (lip-synced) across ISDN lines and ensures
interoperability between different suppliers video conferencing equipment
(actually it doesn't since no-one thought to architect the protocols
to be used on the data channel. Each manufacturer uses a different
link layer packet protocol resulting in no-one talking data to anyone
else - work is ongoing to sort this out, though - see T.12x proposals
for more information).
 
H.320 is a wrapper for several other standards - H.261 for video, H.221
for multiplexing onto ISDN channels, G.7xx for audio, etc...
 
If you want to see H.320 in action with P2P for Windows v1.xx, take a look
at the PictureTel Live-PCS100 system. This uses P2P software and their codec
and gives an idea of the kind of thing to expect.
 
Lakes (P2P v2.xx) will support H.320 audio/video with the BT VC8000 card
(ScreenCall) though only in the UK under ISDN2.

Subject: DDE pasting LINK between Word and Excel
 
I recently tried to paste DDE links between two systems running
the same version of P2P using Excel Version 5.0 for Windows and
Word for Windows 6.0.  Both systems are running DOS 6.3, Windows
3.1, and P2P version 1.0.2.  I tried pasting Excel to Excel, Word
to Word, Excel to Word, and Word to Excel.  In each case I could
paste the information, but could not paste a link.
 
Apparently to paste a link in Excel, you must first select a region of
cells and then paste the link. Also the App. generating the link must
have this function. Word 6 and Excel 5 have this feature.
