Once the PPP link is up with an IP address, the auto dial-in session can be probed. When
detecting either a DTR signal or when any character is received from the serial device connected
to the RS-232 serial port of MultiConnect IP, the Telnet client on board in the MultiConnect IP
establishes a Telnet session to 202.54.39.96 on port 23.
The serial tunnel between the serial device and the Telnet Server terminates in one of the
following conditions.
•
The connection is broken between the serial device and the serial port of the
MultiConnect IP.
•
The Telnet Client on board is terminated.
•
The Telnet Server terminates the session.
Notes:
1.
You cannot open more than one Dial-in session.
2.
The Dial-in session is closed when the configuration session is closed (if opened).
3.
When escape-monitor is enabled, care should be taken during file transfer that the escape-
monitor-string is not part of the data.
