RE: stalling ppp
I had the same problem. My modem used irq 4 under windoze and worked
perfectly. It sucked under Linux. I changed the irq to 2 by running
'setserial /dev/ttyS2 irq 2' as root and everything works great. You can
check your modem by running 'setserial /dev/ttyS2 -G'.
YMMV

Thanks.

I've experienced exactly the same problem, but couldnt figure out how to
fix
it either. To add insult to the injury I have to say that when I boot
windoze
on my computer, connections with both ISPs work flawlessly. It seems
like
windoze somehow reinitiates data transfer when flow control fails, while
ppp
(or modem, or whatever is responsible for the flow control) under linux
does
nothing and the transfer simply stalls. If somebody can help us with
this I
would greatly appreciate it. Below are two logs, first one for the
smooth
connection, and second for the erratic one.
Cheers,
