The latest development is that we have discovered that it will dial when running in Single User mode on his machine but not otherwise.
It will also work perfectly on my machine running either Debian 2.2 or the same version of Progeny that I've installed on his machine and with a simple ATZ initialisation string.
Does this give any clues as to why it won't work on his machine?
Hi Barry, This suggests one of [at least] two things. a) The dialup config changes when the bootup progresses from level 1 (single user) to level 3 (multiuser), though I can't think why that should happen; b) The init stuff that cuts in when level 3 is reached does a hardware probe, and when it finds the modem does something to it which puts it on the wrong foot.
One test to try would be to boot into multiuser with the modem switched off (or even uplugged), then switch it on and try dialling. I guess this would only work with an external modem, though (unless you are prepared to take the chance of "hot-plugging" an internal one).
In any case, don't forget that in these situations 'minicom' is your friend: everything you type goes straight into the modem, and all modem responses are visible as they happen (unless response echo has itself been turned off). So you can see exactly what is happening.
And you can try a raw dialup in minicom from multiuser mode, and compare with what happens from single-user.
Minicom can also be useful for debugging your ISP, by the way!
Good luck, Ted.
