sigh...this is really not that hard.  The secret is to scroll more than one 
line at a time,  if you have received more than one line of data since the 
last scroll.

I wrote some PM code to do fast scrolling (in a real PM program,  not el-
cheapo AVIO) about 6 years ago,  but it wasn't until last year's coloradOS/2 
that I cleaned it up enough to release it.   That was about 1.5 years ago -- 
and I did release it,  but I guess it didn't get much further than the 
coloradOS/2 '94 cdrom.  I'll post it on my bbs.

It is a _very_ dumb terminal program,  and the code is meant to be explained 
by me while I am giving a presentation (ie: there are but few comments in the 
code).

Hint: to see how fast it can scroll,  type a text file name for the port 
(instead of "COM1").
