pppd hangs machine

I'm using pppd 2.1.2 running on Linux 1.3.20 for incoming PPP
modem connections.

The script is something like

exec /usr/sbin/pppd connect '...' -detach silent modem /dev/cua1 38400

with '...' being a 'chat' script that picks up the phone (no
login/password procedure).

This works most of the time, but sometimes it suddenly locks up the

The hardware is nothing special: a 14K4 modem, the usual COM port
(16550?), a Dell 486.

Any ideas?



1. pppd mru negotiation makes pppd hang

When connecting to the local sevice provider, the pppd process hangs if I try
to get it to negociate mru 296.  In fact, it fails if I try to negociate any
mru at all.  The problem must be in my setup, because in Windows winsock is
able to negotiate mru.

Any ideas/pointers to the appropriate references would be appreciated.
