Ubuntu & dial up modem problem T30

[poshgeordie]

2366-8AG T30
Ubuntu Gutsy 7.10 i386.
Currently works on BB
I need to get the TP to work using its built in dial up modem as well as BB.

Checking that modem is recognised, the output of

Code: Select all

sudo wvdialconf /etc/wvdial.conf

gives

Code: Select all

Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Found a modem on /dev/ttySL0.
Modem configuration written to /etc/wvdial.conf.

And attempting to run the modem with a line connected using

Code: Select all

sudo wvdial

gives

Code: Select all

Which indicates no dial tone (also confirmed by ear!).

I've tried a couple of modem boards and a couple of modem cables.
I guess there could be a mobo fault, but nothing's picked up on PC Doctor.
I'm trying to assume that the problem is software based not hardware, but anything's possible!

Any ideas anyone?

The T30 modem uses a AC97 modem adapter.

Thanks DKB

I don't think the T30 has the same modem chipset, but will be useful for 600E owners.

I have no idea where I got 600E from. Must be from another post I read recently. I edited the previous post above.

Not a problem!!

I'm not convinced that I have a driver problem, since it works all the way up to the point where it doesn't have a dial tone, which may be a config issue.

I'll try with another T30 to make sure there isn't a hardware fault and then try your solution.

Many thanks
