I've been trying to set up pppd on a netbsd-1.3.2 running a sparc IPC.

When running with debug mode I get the following:

pppd /dev/ttyb 9600 crtscts defaultroute debug connect /etc/ppp/test.sh  

pppd[1659]: pppd 2.3.1 started by andrew, uid 0
pppd[1659]: Serial connection established.
pppd[1659]: Using interface ppp0
pppd[1659]: Connect: ppp0 <--> /dev/ttyb
pppd[1659]: sent [LCP ConfReq id=0x1 <magic 0x7a22c0f3> <pcomp> <accomp>]
pppd[1659]: Modem hangup
pppd[1659]: Connection terminated.
pppd[1659]: Exit.

  -or-

pppd /dev/ttyb 9600 crtscts defaultroute debug silent connect /etc/ppp/test.sh

pppd[1682]: pppd 2.3.1 started by andrew, uid 0
pppd[1682]: Serial connection established.
pppd[1682]: Using interface ppp0
pppd[1682]: Connect: ppp0 <--> /dev/ttyb
pppd[1682]: Modem hangup
pppd[1682]: Connection terminated.
pppd[1682]: Exit.


cat /etc/ppp/test.sh

#!/bin/sh
echo 'Dialing...'
rc=4
while [ $rc != 0 ]; do
        chat -v -f /etc/ppp/test.chat
        rc=$?
done
echo 'Done\n'
exit 0

cat /etc/ppp/test.chat

ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO ANSWER"
ABORT "BUSY"
"" "at"
OK "AT&FM0"
OK "ATDT1231231234"
CONNECT ""
"gin:" "USER"
"sword:" "PASSWORD"

The chat script succeeds, but it just wants to hang up when it tries 
anything else.  I've tried many many of the options to try and get this
to work, to no avail... i'm getting frazzled.  Any assistance would be
appreciated.

thanks
