Could you be more specific about "chokes" ? ;)

Can you install something like minicom to try making it dial by hand?

First of all, check you can talk to it by just typing "AT" and pressing
enter, it should answer with "OK"

You can reset the modem with "ATZ" and get it to dial the number with
"ATDT" and follow with the number, eg dialling up to where I work would be

Eventually, you should see a "CONNECT" from the modem, possibly with a
speed following it.

At this point you may need to press enter to grab the attention of the
modem rack that you're dialling into, and persuade it to give you a login
prompt instead of waiting for a PPP sequence.  You can then use the
account name and password to log in.  If you log in succesfully, you will
see a whole big bunch of apparently random characters come back at you,
which is the modem rack trying to start a PPP session.  If you don't log
in succesfully, it will either ask you to reenter your details or just
drop the connection.  In either case, it should prove to be useful

Have you verified this with a phone on the same line?

hmm, no, I suspect not

see above :)

Just out of interest, what sort of modem is it?
