A21P ,LInux slackware 10 , pcmcia Xircom CI-euro isdn

[Ted Frater]

Despite looking extensively elsewhere on the net, Ive had no success in finding a way to get the above passive (infineon chipset) isdn pcmcia to be recognised and working with linux slackware 10.
Can anyone help at all with this problem?
I also have the active Psion Dacom isdn card( rockwell chip set) with the isdn adapter. Cant get this one working either!
am currently using an external Multitech off the serial port connecting at 64k. Standard single channel isdn in the UK.
