Question OPTION GSM card under Linux 

Forum: PCMCIA Serial and Modem Issues

I have bought an OPTION GSM-only PCMCIA card and am trying to get it to work under Linux, Kernel 2.2.5 (SuSE 6.1), PCMCIA driver 3.1.5.
It is recognized by cardmgr and cardinfo displays it as a serial or modem card.
Cardctl displays it as :
Socket 1:
  product info: "Option International", "GSM Data/Fax/SMS Modem", "V1.300", ""
  manfid: 0x0013, 0x0000
  function: 2 (serial) 

But unfortunately, it seems not to work ! When I start minicom and try to connect to /dev/ttyS1, which is what the serial start command displays as the port, the modem does not answer to AT commands.

Question : Is this one of the kinds of modems that tell they are one but in reality need a (Windows) driver to function like one ? Or is it just a configuration issue ?

Please help !
