If I recall, Minicom may not support DTE speeds above 9600. 3Com US Robotics
modems will never connect above the DTE speed (what's the point of connecting
at 33.6k if you can't push more than 9.6k across the serial port?). Check
your DTE speed in Minicom.
If Minicom is incapable of supporting speeds above 9600, and you have no
alternative communications program (such as Kermit), you may be able to use
a utility called setserial to fake out the baud rate. Usually this program
is used to reconfigure the kernel so that a baud rate of 38400 configures
the serial port for 115.2k or 230.4k instead, but maybe it has an option
Just in case though that your ultimate goal is to get PPP up and running, but
are stuck at the Minicom level simply for purposes of test it, let me tell you
in advance that PPP doesn't have such problems, and you may be better off
forgoing Minicom and trying PPP immediately. You may not have this problem.
