Hi all,

I'm having very basic trouble with a modem card. It's an old one, and it's
possible it's dead, misconfigured, or otherwise not functioning.

However, my problem is more basic than that, even. I can see from hwinfo that
the thing was probed successfully, and it has created /dev/ttyS0 and
/dev/ttyS1, but I don't know which is the modem, and which the serial port, and
I am having difficulty finding out.

I tried using minicom to connect to the thing and sending it "AT" and "ATZ"
commands (memory vaguely suggested that one of these was supposed to get a
reply from the modem) but I couldn't get a response out of either /dev/ttyS0 or

Any suggestions on how to identify it, or determine if the card is in fact
misconfigured in some critical way (or dead)?
