Terminal (Program Port/Telnet) Commands
Overview
There are two types of terminal communications available on NetLinx Integrated Controllers: 
Program Port - The "Program" port is a RS232 port located on the rear panel of the Master that 
allows terminal communication with the Master. This type of terminal communication requires that 
you are physically connected to the Master to access the configuration options and commands 
supported. Since this method of terminal communication requires physical proximity as well as a 
physical connection to the Master, it is the most secure form of terminal communication. 
For this reason, all Security Configuration options are only available via the Program port (and 
cannot be accessed via Telnet).
Telnet - This type of terminal communication can be accessed remotely, via TCP/IP. It is a less 
secure form of terminal communication, since it does not require a physical connection to the 
Master to connect. Further, the Telnet interface exposes information to the network (which could be 
intercepted by an unauthorized network client).
Refer to the Terminal Commands section on page 97 for a listing of all commands available in a terminal 
session. 
Note that all commands in the table are available for both Program Port and Telnet sessions, with two 
exceptions: "Help Security" and "Resetadminpassword". These commands are only available via a Program 
Port connection.
Establishing a Terminal Connection Via the Program Port
To establish a terminal session via the Program Port, the PC COM (RS232) port on your PC must be physically 
connected to the Program port on the NetLinx Master.
You will also need to know the current baud rate setting for the Master, so that you can verify that it matches 
the settings on your PC.
1. In Windows, go to Start > Programs > Accessories > Communications to launch the HyperTerminal 
application to open the Connection Description dialog. 
2. Enter any text into the Name field and click OK. This action invokes the Connect to dialog.
3. Click the down-arrow From the Connect Using field, and select the PC COM port being used for 
communication by the target Master and click OK when done.
4. From the Bits per second field, click the down-arrow and select the baud rate being used by the target 
Master. 
5. Configure the remaining communication parameters as follows: 
6. Click OK to complete the communication parameters and open a new Terminal window.
7. Type echo on to view the characters while entering commands. If that does not work, press <Enter> key 
on your keyboard.
It is recommended that you make initial configurations as well as subsequent 
changes via the WebConsole. Refer to the Onboard WebConsole User 
Interface section on page 21.
