Huh? There are times when doing this could be very appropriate (of course
if it isn't abusing the situation or being greedy with shared resources).
In a former life I had access to a modem bank (not in my control) which was
configured to throw you off the the line after inactivity timeouts of 10
mins or so, in a situation where it would throw you off after 120 minutes
anyway.
Without sending echo-requests I would come back from a coffee or a phone
call or some other extended distraction to find myself disconnected. A
real pain, especially since the ppp IP addresses were llocated dynamically
- which meant that - unless you were lucky to get the same IP address
re-allocated when you re-connected - there was no way to re-establish any
active, eg, telnet sessions from a different IP address (where I might have
had an editor running or whatever) :-(

Yes, agreed. Solid advice. And in the above case I couldn't fix the real
problem and found another solution.

With all due respect... don't jump to conclusions!
I'm my own ISP! I have my linux box at work with a modem hanging off it or
(more usually) off another box nearby in the office, and I can ring from
home and connect directly to it for as long as I like. (Granted, I'm very
lucky to be able to do this. No time-charged local calls here either).
I also have other dialup internet access via shared modem banks, but in
this case I'm careful not to abuse that (not that I have any need to:)

Good ideas to follow up...
