It would appear that your modem is autobauding and setting the DTE speed
on it's own. Different modem vendors have different ways of fixing the DTE
speed of the modem. Some won't let you do it, especially WinModems which
lose most of the few brain cells they have without Win32 support.

You might be able to kill two birds at one time (one you didn't know was
there 8{). If you use mgetty, it can allow FAXes as well as regular getty
support and decent auto-ppp support. As it disables auto-answer and issues
a 'ATA' command when it sees 'RING', it always reminds the modem of the
DTE rate desired.
If you have a voicemail modem, it can even be a DTMF-menu-enabled
voicemail system. I have a great web script for Apache to be the rest of
the answering machine. My wife loves it and the CallerID support is cool.
Hope this helps - Jy@ (JWyatt@RWSystems.net)
