I have been using chat for the past two years so it seems to be working ;)

I had a look at the ppp-go script that Slackware uses and _ages_ ago I
modified it so that non-root user could dial up, but apart from that I
have just left it. If it ain't broke, don't fix it :)

In other words I have to know the connect speed before I connect. NOt
really the purpose of the exercise(sp???)

Ah..... - chat basically talks to the modem yeah?? TBH I am getting lazy
and can't really be bothered to muck around too much with this. But I do
remeber a while ago I was getting connection speed logged through syslog
and I was wondering if I was being dumb or something....
