TCP Port Numbers for Serial Ports

The TCP port numbers by default start at 7001 for serial port 1 and increments
up to the number of serial ports that your CS unit has. For example, an CS
with 8 serial ports have TCP ports 7001 through 7008. The CS administrator
may change the default port numbers, so if you use the defaults and they fail,
check with the administrator to find which port numbers to use.

To Use Telnet to Connect to a Device Through a Serial Port

For this procedure, you need the hostname of the CS or its IP address and the
TCP port number for the serial port to which the device is connected.
telnet hostname | IP_address TCP_port_number

To Close a Telnet Session

Enter the Telnet hotkey defined for the client. The default is "Ctrl ]" and "q"
to quit.
