Serial Telnet Client

Serial Telnet Client

This section describes how to configure your Ethernet Adapter as a serial telnet client.

Telnet is a method to connect and remotely log-in to a host computer or network device. 
The host computer or device must be running a telnet server for this service to be available. 
Once the telnet session is established from the Ethernet Adapter, any data received by the 
serial port of the Ethernet Adapter is sent to the host. At the same time, any data returned 
from the host is sent out the serial port of the Ethernet Adapter. Typically, the serial port of 
the Ethernet Adapter is connected to a serial terminal or a computer that is running terminal 
emulation software.

Serial Telnet Client Configuration

To configure your Ethernet Adapter as a serial telnet client, perform the following steps:

1)

Complete the Basic Radio Configuration instructions described in 

Chapter 4

.

2)

Complete the Network Configuration described in 

Chapter 4

.

3)

Complete the General Serial Configuration described in 

Chapter 5

.

4)

Click on the Serial tab, and then select the Protocol tab. 

5)

Select the Telnet option in the Protocol list. 

6)

Click on the Telnet tab at the top of the panel. There are two methods that can 
be used to establish a telnet connection, Wait for Keystroke and Command 
Prompt
. The next two sections describe these methods and the configuration. 

Wait for Keystroke Connection Configuration

The wait for keystroke connection method establishes a connection to a specific telnet host 
when the user presses a key on the telnet terminal window. When the telnet connection is 
closed, the Ethernet Adapter will wait for a keystroke to connect again.

To configure your Ethernet Adapter as a serial telnet client using the wait for keystroke 
connection method, complete the configuration described in 

Serial Telnet Client 

Configuration

 steps 1–6, and then perform the following steps:

1)

Click on the wait for keystroke button.

2)

In the Connect to IP field, enter the IP address of the device to which the 

Ethernet Adapter will establish a telnet connection.

3)

The default Connect to Port value, 23, is the industry standard port number 
for telnet connections.
