How to configure Xircom pcmcia card to Red Hat 7.1?

I currently have an IBM Thinkpad with a built in 56k modem. RedHat 7.1 does not recognize my internal modem. I used a Xircom Ethernet 56 + 100 card. Linux knows the card is there. However, I have been unable to set it up. Please help is possible.

Some Linux distributions, including Slackware, use a BSD arrangement for system startup scripts. If /etc/rc.d/rc.M exists, your system is in this group. The script rc.pcmcia, installed in /etc/rc.d, controls starting up and shutting down the PCMCIA system. "make install'' will use the probe command to determine your controller type and modify rc.pcmcia appropriately. You should add a line to your system startup file /etc/rc.d/rc.M to invoke the PCMCIA startup script, like:

   /etc/rc.d/rc.pcmcia start

It does not really matter where you insert this line, as long as the
PCMCIA drivers are started after syslogd.
