GSM modem access on a Linux mobile device (e.g. N900)

Question

I am trying to access a GSM mobile dialing modem, so I can send him AT commands. Instead of programming, I tried to run a test run using minicomon the phone. The problem is that I can’t find the device I have to connect to, I tried / dev / tty 0 tty1, as well as ttyS0 and the same, but none of them answered my command AT.

So what should I do? Is it possible?

Platform : Nokia N900 (works maemo linux)

Answer 1

This was resolved when I ran:

pnatd /dev/tty

simple, that simple, although not documented anywhere, I think.
