Sad Xircom CEM33 does not work properly with pcmcia-cs 3.1.8  

Forum: PCMCIA Multifunction Card Issues
Date: 2000, Jan 14
From: Martijn Anthonissen martijn

When I tried upgrading my kernel from 2.2.12 to 2.2.14 the modem part of my Xircom CEM33 card stopped working. I've looked into this a little, and the problem seems to be with the pcmcia card services.

The combination kernel 2.2.12 + pcmcia-cs 3.1.2 worked flawlessly. My modem was recognized and placed on /dev/ttyS3.

When booting kernel 2.2.14 + pcmcia-cs 3.1.8, the modem is placed on /dev/ttyS2, and it doesn't work. Only the ethernet part of the CEM33 functions.

At this point I did some experiments. Booting 2.2.14 without any of the 3.1.8 modules and then inserting the "old" 3.1.2 modules by
      insmod -f /lib/modules/2.2.12/pcmcia/pcmcia_core.o
      insmod -f /lib/modules/2.2.12/pcmcia/i82365.o
      insmod -f /lib/modules/2.2.12/pcmcia/ds.o
      insmod -f /lib/modules/2.2.12/pcmcia/xirc2ps_cs.o
      insmod -f /lib/modules/2.2.12/pcmcia/serial_cs.o
leads to a properly functioning modem.

However, booting 2.2.14 and inserting the new 3.1.8 pcmcia_core module and for the four other modules the 3.1.2 ones places the modem on the wrong /dev/ttyS2 device again.

I thought I'd also try and compile an unstable kernel, 2.3.39, as I'd read that the pcmcia code will be included with the kernel. When booting 2.3.39, the modem is placed on ttyS2, as with the 3.1.8 modules.

Below, a typical piece of my syslog is listed, including an unsuccessful dial-in attempt.

I hope someone can help out, TIA,

Martijn
