/* "Server" and "client" are fuzzy concepts with the Pilot. The Pilot
 * initiates conversation, and the desktop sits passively and listens, so by
 * unix networking standards at least, the desktop is the server and the
 * Pilot is the client. However, once a connection is established the
 * desktop initiates all further actions while the Pilot sits, passively
 * allowing the desktop to rummage through its databases. Thus the desktop
 * could be called a client.
 *
 * All normal Pilot hot-sync programs should be "acceptors" that sit around
 * waiting for a pilot to connect, using the Unix bind/listen/accept
 * sequence. The test-connector companion to this file is effectively a
 * "fake Pilot" that uses connect to simulate a Pilot connecting. Note that
 * either side can transmit and receive data, as long as they agree on which
 * one is going to be talking.
 *
 * This pair of programs use a pty to simulate the first stages of a Pilot
 * communcation -- CMP exchanges, and baud rate matching. Note that a pty is
 * used to let the two programs talk together, and that no attempt has been
 * made to properly allocate a pty.
 *
 * Also note that dlp_AbortSync is used, instead of EndOfSync. That is
 * because the normal EndOfSync proceedings involves sending a padp packet,
 * which would not work as neither side is expecting such a packet.
