Method One, set the two ends of the serial port as PPP protocol and configure the IP address can be
Method II, PAP certification
First step: (Master) Select a port master port
Step two: (master) Setting PPP for unilateral verification of Pap PPP Authentication-mode PAP
Step three: (master) set the local user name and password and set the user's service type Service_type PPP to PPP type
Fourth step: (BE) Select another port for the authenticated party
Fifth step: Set the port as the PPP passive authenticator and set the authenticated user name and password to be the Primary authenticator user password PPP pap local-user principal party user name password master user password
Method three, CHAP authentication
First step: (primary) PPP Authentication-mode CHAP set PPP single-sided verification of Pap
Step two: (master) set the local user name and password and specify the service type as PPP (note that the user names on both sides can be different but the passwords on both sides must be the same)
Step three: (master) use peer-to-peer user name to initiate PPP CHAP authentication on the port
Fourth step: Set the user name and the same password, and specify the type of service as PPP
Fifth step: (by) Starting PPP CHAP authentication on the port with the peer user name
