Chapter 7 – Telnet Dialout
Introduction
Telnet Dialout Feature
The Telnet feature allows you to access the serial port and establish two-way traffic between the
Telnet/RAW-TCP client and the serial device.
This chapter provides examples of a Telnet client on an IP network (over the modem port) connecting
to a remote serial device. The MultiConnect IP acts as a Terminal Server using the Telnet dialout
feature.
Features
The MultiConnect IP, acting as a Terminal Server, accommodates the following features:
•
Authenticates the serial port.
•
Monitors and waits for activity on the standard Telnet port (23) or user-defined RAW-Socket.
•
Opens the serial port from the command prompt (manual dialout) .
•
Opens the serial port directly (auto dialout) using a TCP Client according to the configured
port-number.
•
Switches between the command prompt and a dial-out session when the session is in Telnet
mode.
