The PPP link junk is for dial-up as far as I know, and I don't know of anyone in my circle of resources that has that set up. If you are going to use dial-up anyway then just dial into the number you have assigned to the CCA and connect using 115200 N 8 1 (if it's 9006.6) or 19,200 N 8 1 if it's less than 9006.6. It's best to use ProComm because the protocol best used is ANSI-BBS, and there is a special pansi3.kbd file on the 9006 utility floppy that does the keyboard mappings.
