Using PCOMM

Reference: getting Pcomm to work with trailblazer

Pcomm has a "feature" that is a blessing for some, and a curse for
others.  It has to do with the ability to automatically sync the TTY to
a different baud rate.  Here is what I intended:

        1) You can't remember if a remote system has 2400 baud or 1200
        baud modems, so you pick 2400 baud to call them.

        2) Your TTY (and modem) are set to 2400 baud to place the call.

        3) Lo and behold, they only have 1200 baud modems and you get
        the "CONNECT 1200" message.

        4) At this point, your modem has sync'ed at 1200 baud, the
        remote system's modem has sync'ed at 1200 baud, BUT THE TTY IS
        STILL AT 2400 BAUD!

        5) Pcomm will check the return message from the modem (ie. the
        "CONNECT 1200") and determine that the baud rate to the TTY
        should be changed.

For you guys with trailblazers locked at 9600 baud, this is definately
not what you want.  You need to disable the "autobaud detect" feature of
Pcomm.  The way to do this, is to change all the connect strings to
"CONNECT".  Pcomm checks to see if the connect strings are the same; if
they are, it skips the autobaud stuff.

Also, if the trailblazer is locked at 9600 baud, shouldn't all the
dialing directory entries have the baud rate set to 9600 rather than the
speed at which they answer???

I'm gonna have to get me one and play with it a few days...
