Modem connection disrupted after upgrade with apt-get



I have just completed an 'Upgrade' via apt-get (NOT a 'dist-upgrade'). The only resulting problem I'm aware of is that I can no longer dial out.

The TR (is that actually DTR) and RTS indicators on the modem are switching on and off - off for about half a second, on for about a second. If wvdial catches them in the 'off' stage dial up begins successfully but is immediately killed by the 'on' part of the cycle.

Can anyone shed any light on why this might be happening, or how I can find out, and what solutions there might be.

Here are the results of statserial:

Device: /dev/ttyS1

RI      22    9      in          0   Ring Indicator

Any help would be graetly appreciated.

Thanks, Alisdair
