Debian Lenny: ProLiant GL360 G6: GSM modem at /dev/ttyS0 not recognized

Hello,

I have a fresh installed Debian Lenny, which does not recognize a GSM modem Siemens TC35 at /dev/ttyS0. I try to access the modem with smstools from the debian repository.
The modem is completely accessible on Windows via Hyperterminal. I am not very familiar with Linux and would appreciate any help.

ls -la /dev/ttyS*
crw-rw---- 1 root dialout 4, 64 2009-07-24 02:36 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 2009-07-24 02:50 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 2009-07-24 02:04 /dev/ttyS2
crw-rw---- 1 root dialout 4, 67 2009-07-24 02:04 /dev/ttyS3

setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

fuser -s /dev/ttyS0 returns nothing.

I do not get anything from minicom.

I tried to change the flow control to "hardware" on the modem, but this did not help.

I tried the tips here to check if the modem is connected http://axion.physics.ubc.ca/modem-chk.html but no modems got recognized.

Thanks,
Erik

Shalom Erik,

I would suggest going to the modem manufacturers website and looking for drivers for your Linux distribution.

If no drivers exist for this Distribution, you may wish to consider another distribution of Linux.

How do you know that the port it's connected
to is "/dev/ttyS0"? Is there more than one
9-pin serial port connector on this system?
Have you tried the other(s)?

I'd expect that, if no one is using that
port.

When you do _what_? ("-p pty" option?)

I'd start by forgetting the modem, connecting
pins 2 and 3 on a serial port, and then
trying to talk to the piece of wire. When I
knew that I could talk to such a loopback
connector, then I'd try connecting a modem.

That would seem to rule out many obvious
hardware problems.
