Idea: SOLVED! kind of...xircom card OR modem work .. both do not

Re: Question: tecra 8000 rbe-100 and lucent modem red hat 6.2! (ritesh patel)

i have gotten the card working. i am using dhcp. when the card works the lucent modem inside this laptop does not. if i disable pcmcia (by editing /etc/sysconfig/pcmcia and making PCMCIA=no) then the modem works.

i am new to linux. can someone help me in diagnosing why both do not work together?

my xicrom networt card and lucent modem both seem to want to use the same irq as shown in the output below: 

~ >cardctl config
Socket 0:
  Vcc 3.3V  Vpp1 3.3V  Vpp2 3.3V
  interface type is "cardbus"
  irq 10 [exclusive] [level]
  function 0:
    io 0x0400-0x047f [32bit]
Socket 1:
  not configured
~ >setserial -g -v /dev/ttyS14
/dev/ttyS14, UART: unknown, Port: 0x0400, IRQ: 10
~ >

when i exclude irq 10 in /etc/pcmcia/config.opts the network card still works but the modem still does not. i have also tried excluding the port by including a line like

exclude port 0x0400

in /etc/pcmcia/config.opts but that did not work either. since there is almost no documentation on the ltmodem package i am left with playing with the pcmcia settings. any suggestions?

It may be a misfeature of the ltmodem driver

The ltmodem driver may not work properly in an interrupt-sharing
arrangement.  There is no way to force the CardBus card to use a
different interrupt; this is enforced by the hardware in your laptop.
Unfortunately, since the ltmodem driver is binary-only, there is not
much that can be done to try to debug the problem.

Ok: problem solved!

thank you for the reply. i was able to get both the network card and modem working by moving the load of the ltmodem driver to the start of /etc/rc.d/rc.sysinit. the ltmodem installation program loads the driver at the end of /etc/rc.d/rc.local.

for anyone else running a tecra 8000 following is my configuration:

i have a xircom xbe-100 network card and the internal modem is a lucent winmodem.

in the bios card - cardbus/16 bit. autoselect also works. /dev/ttyS0 0x03f8 irq 4 --> serial port 1 (used for my pilot) /dev/ttyS1 0x02f8 irq 3 /dev/ttyS2 0x1c00 irq 3 --> modem /dev/ttyS3 0x02e8 irq 3

/dev/modem is linked to /dev/ttyS2
