^S/^Q problems at either the modem side or the ppp side?
"+++" tripping up the modem?
I just had the unexpected pleasure of using PPP over the 56k modem on
my vaio portable for the last 7+ days while Athome/AT&T/TCI were
smearing chicken blood on the routers to drive out the evil spirits.
(Or at least thats what I got out of the explanation that the "tech"
support people gave me.)
I would notice times when the PPP connection only stayed up for a few
minutes, but I never saw times when the PPP had to be killed and
restarted before it would talk again. This was a shared dialup so I
would kill the daemon every few hours when I wanted the connection to
stay down for a while. (So the daemon never got really old.)
BTW. This running -current.
As it was, NetBSD-current was flexible and robust enough that I could
just point the default route from my main router / workstation at the
vaio portable. On the vaio I ran a NAT, a gif ipv4-ipv4 tunnel, pppd
in demand-dial mode. It all just worked. I was also pleased to see
that the pppd was smart enough to ask for its old IP address back when
it called back. Neat!
