QNX PPP Issue

I am trying to get PPP running on QNX and have followed the instructions in the following link section, "Networking QNX Neutrino using PPP:

http://www.qnx.com/developers/docs/6.4.1/ide_en/user_guide/target.html

The strange thing is using the Windows PPP settings and the following command it actualy worked once but never again:

"pppd debug nodetach nocrtscts auth +chap 10.0.0.1:10.0.0.2 netmask 255.255.255.0 /dev/ser2 115200"

And by worked I mean using ipconfig I could see my IP address has been assigned to the Windows PPP connection. I then retried it and it did not work. Below is the log I get when the connection fails, Windows reports “Error 734: The PPP link control protocol was terminted”
It appears to me it is authenticating OK but failing after that. I am slightly miffed as to why it worked once and once only. Any advice is appreciated. Thanks.
