Chapter 6 – Serial-to-Network Connectivity Using Serial Dial-in

Command Line Interface and Application Examples for Multi-Tech Systems, Inc. IP Modules (S000368F) 78

Scenario 1 – Manual Serial Dial-in

Invoke # telnet <ip-address> <port> at the command prompt. Once the session is opened successfully, there can

be two-way traffic between the serial device and the remote server.

• You can switch from Command Prompt to Dial-in session using the restore session command.

• You can switch from Dial-in session to Command Prompt using <escape-monitor-string>.

Notes

• Once the physical link is up and the PPP interface has acquired an IP address, the IP module is ready to

use.

# telnet 202.54.39.96 23

• The Telnet client on board in the IP module establishes a virtual serial tunnel between the serial device and

the Telnet Server.

• You cannot open more than one dial-in session.

• The dial-in session is closed when the Telnet session is closed.

• When escape-monitor is enabled, care should be taken during file transfer that the escape-monitor-string

is not part of the data.
