Problem with mgetty and USRobotics Courier when >2400 bps

Hi,
check the calling modem. It really works with a USR Courier V.34, with
14.400, 28.800, whatever. No magic needed.
(My setup string for USR Courier basically does little more than set the
modem to AT&F1).
If the modem repors NO CARRIER, it usually really is a communication/setup
problem between the modems. It is nearly never a mgetty problem.
