Hi,

I have a this card (see $subj) and cannot make it run in linux.
Description of the card can be found here:
http://www.mc-technologies.net/html/cellular/gcc.htm

/var/log/messages when I insert the card:
Jan 23 09:20:25 dhcp23 kernel: PCMCIA: socket c62dc82c: unable to apply
power.
Jan 23 09:20:26 dhcp23 kernel: cs: memory probe 0xa0000000-0xa0ffffff:
clean.
Jan 23 09:20:26 dhcp23 cardmgr[782]: socket 0: Serial or Modem
Jan 23 09:20:26 dhcp23 cardmgr[782]: executing: 'modprobe -v serial_cs'

Jan 23 09:20:26 dhcp23 kernel: ttyS0 at I/O 0x3f8 (irq = 3) is a 8250
Jan 23 09:20:26 dhcp23 kernel: ttyS4 at I/O 0x400 (irq = 3) is a

Jan 23 09:20:26 dhcp23 cardmgr[782]: executing: './serial start ttyS0'
Jan 23 09:20:26 dhcp23 kernel: serial8250: too much work for irq3
Jan 23 09:20:27 dhcp23 last message repeated 5 times
Jan 23 09:20:27 dhcp23 cardmgr[782]: executing: './serial start ttyS4'

When I start minicom for ttyS4 it shows it is online but the modem doesn't
reply to any AT command. This is the output of chat programme:
# chat -v -s '' ATZ OK
send (ATZ^M)
expect (OK) ATZ
alarm
Failed

I tried it in 2.4.21 too but there was no change.
I attach a log from windows where it works fine.
According to this log I set up the speed, data bits, parity etc. in linux
to the same values but it doesn't help.

Does anyone have the card running under linux ?

Thanks for any advice.
