Replace the IP address by the one that is actually assigned to the DKVM-IP1 switch. This will 
prompt for username and password in order to log into the device. The credentials that need 
to be entered for authentication are identical to those of the web interface. That means, the 
user management of the Telnet interface is entirely controlled with the according functions of 
the web interface. 

Once you have successfully logged into the DKVM-IP1 switch a command line will be 
presented and you can enter according management commands. 

In general, the Telnet interface supports two operation modes: the command line mode and 
the terminal mode. The command line mode is used to control or display some parameters. 
In terminal mode the pass-through access to serial port 1 is activated (if the serial settings 
were made accordingly). All inputs are redirected to the device on serial port 1 and its 
answers are displayed on the Telnet interface. 

The following list shows the according command mode command syntax and their usage.

 

 

help  

 

Displays the list of possible commands 

 

cls 

 

Clears the screen 

 

quit 

 

Exits the current session and disconnects from the client 

 

version

terminal 

 

Starts the terminal passthrough mode for serial port 1. The key sequence esc exit 
switches back to the command mode. The command has an optional parameter (1 or 2) 
to select the desired serial port for passthrough access.
