PCMCIA modem card is not responding

[Prabhakar Kalasani]

Leonardo,
The drivers being loaded with cardmgr only and it uses /etc/pcmcia/scripts
only.
I could detect correctly there is no problem in it, the problem is when i
send modem string through Minicom , I'm not getting "OK" responce from the
card.

It might be the problem read/write into the card. But i don't know how ?

Best Regards,
Prabhakar

Are the drivers being loaded? This done by cardmgr, and it uses the
/etc/pcmcia/ scripts (network.options, memory.options). If you got a
consistent response from cardctl for

#cardctl ident

Or something like that, your pcmcia interface should be working.

Remember that pcmcia drivers should be loaded by cardmgr, not by a simple
insmod. This is because the driver waits for a CARD_INSERT event, which's
generated by cardmgr.
