Hi,

after connectig a new USR-Courier to the Portmaster I would like
to set the serial speed of the modem serial port directly from the
portmaster to 115200 KBaud.

How to do it?

P.S. I cannot remember, but it should be commend like "tip" under Unix
for setting the modem parameters from the AT-prompt.
