I'm trying to set up two routers connected to each other using RS232 (smartSerial) cables (one DTE, one DCE). Have set the serial ports into 'async mode dedicated', and encapsulation ppp but I cannot get the link to come up. The status (on both sides) shows line up protocol down, and the link flaps between 'up' and 'reset'. Debug ppp shows the Req's going out but no replies. Can anyone suggest what I might be doing wrong?
I have this problem too.
