GVC PCMCIA modem not recognized

[Dan Christensen <jdc@uwo.ca>]

I'm trying to get a GNET/GVC PCMCIA 56k modem to work under linux:

Model:  GPCM-56/AMC (MQ4FM560)
Kernel: 2.4.22, using in kernel pcmcia modules.  Compiled from source.
Debian pcmcia-cs userspace utils, version 3.2.2-1.2

When I insert it, I get one high beep, and one low beep.  Here are the
messages I get in my log file:

cardmgr[352]: socket 1: Serial or Modem
cardmgr[352]: executing: 'modprobe serial_cs'
kernel: isapnp: Scanning for PnP cards...
kernel: isapnp: No Plug & Play device found
kernel: Serial driver version 5.05c (2001-07-08) with 
  MANY_PORTS SHARE_IRQ SERIAL_PCI ISAPNP enabled
kernel: PCI: Found IRQ 11 for device 00:1f.6
kernel: PCI: Sharing IRQ 11 with 00:1f.5
kernel: PCI: Sharing IRQ 11 with 02:03.0
cardmgr[352]: get dev info on socket 1 failed: No such device
kernel: register_serial(): autoconfig failed
kernel: serial_cs: register_serial() at 0x03f8, irq 3 failed

The GVC website 

  http://www.gvc.ca/cgi-bin/display.cgi?displayProd=37

says that the card works under linux, and I also read this elsewhere
on the web, but I haven't had any luck.

Any suggestions?

Thanks,

Dan
