1. Help: Serial Link not 8-bit clean!

Setup:
Redhat 6.1 with a Wavecom (GSM) modem.

If I use minicom to dial the remote ISP, everything works fine, a
connection is made, and the authentication works.

If I then use ppp with (ppp-on, ppp-on-dialer) scripts to dial the same
ISP, I get the following message in /var/log/messages

Serial connection established
Using interface ppp0
Connect: ppp0 <--> /dev/tty0
LCP: timeout sending
Connection Terminated
Recieve Serial Link is not 8-bit clean
Problem: all had bit 7 set to 0
Hangup (signup)

Can anybody help solve this issue, I've seen similar postings before,
but there is not a clear solution.

thanks

Dave
