I just upgraded my system from RedHat 5.2 to Mandrake 7.0 and my Sierra Wireless Modem/Cell Modem card has stopped working. I applied Jeff Schoby's patches for the aircard to a version 3.1.9 PCMCIA source and recompiled/reinstalled. I just mention this for completeness. The patch dosn't touch the serial_cs driver which is causing me the problem. I've also checked against an unpatched 3.1.9 install.
The problem is that the modem does not respond. If I load minicom, I can't get it to return an OK to ATZ and minicom hangs and will not quit if I try to shut it down until I remove the card. The card works in a Windows laptop (I can get an OK back from a terminal program) and should appear to be a generic modem. A Megahertz modem card works fine in this installation, From /var/log/messages:
