Direct serial connection for PPP on SCO OSr5 using Morning Star pppd?

[Guest_imported]

I'm having a terrible time getting this to work. I'm attempting to establish a PPP session over a serial link using Morning Star's pppd. This will be communicating with a Windows CE device. I need it to *not* authorize, as I won't be logging in. This Windows CE device has a initialization "prolog" that consists of a simple ascii handshake. The client sends "CLIENT", and the server responds with "CLIENTSERVER", then the ppp session starts. I can accomplish this w/o issue on my Debian 2.2r5 box using the pppd that comes with the distro. I simply define a chat script that includes this simple ascii handshake. I understand I can accomplish the same on SCO using uucp. My main question; can I facilitate a direct serial connection w/o requiring authentication using Morning Star's pppd? I simply need it to listen on a serial port, wait for the "CLIENT", send the "CLIENTSERVER", then start the ppp session. I've read every bit of documentation I could find, but still having issues. Thanks!
