Thanks for that. I have to admit I didn't think to look in my syslog and see
what was mentioned there. I will a bit later when I am back on the other
machine.
But the modem connects all right and remains connected. Is connected to this
machine also running etch at the moment. Just pppd has dropped off the modem
a couple of times lately. It doesn't happen all that often, but it happens
and I thought someone else might have experienced some sort of behaviour like
this as well. Like the Chinaman said when his horse died, it's never done
that before.
I will try the pppd-debug option. Have seen it there in the past and never
thought I needed it. Have had this modem for almost ten years and no
problems, had it checked through my ISP just recently. I should have it
connecting a little slower, according to the ISP, but this modem is built to
make the most out of copper line.
Only since Etch has this been happening and only for the last couple of weeks
upgrades? So I just wondered?
Thanks for your help, sorry for being so verbose.
Be well,
Charlie
