Enter the Telnet Server Port Number (TCP/IP port number) for the terminal server and serial
port.
To find the Telnet Server Port Number, double-click the configuration device’s listing to go to
its website.
Then, go to the
Status & Configuration
page and locate the
Local Telnet Port Number
row,
and select the number for the serial connection, Port 0 or Port 1, that you wish to use with this
connection.
»
Select Start this connection automatically when Windows starts.
»
If you do not select this option, the connections will not been made unless you provide the –a
command line option that instructs the launcher to start all connections.
»
Click Create Connection to save the information on the newly configured connection.
Notice that Virtual Port Pair 0 is no longer bolded, indicating that the port pair is already in
use and you cannot configure another connection using the same pair. To create another VCP
pair for use by your second (or subsequent) connection, click Create New Pair and repeat the
above process.
»
You can now start your legacy serial application and open virtual COM port CNCA0 and
communicate with the remote serial device attached to the terminal server.
Edit port names
Some serial applications are unable to connect to a serial port named using a form other than
COMm, where m is the port number. Since com0com ports are named CNCAn and CNCBn
by default, this can cause problems. If you encounter this problem, ComNet Terminal Server
Configuration application allows you to change the names of virtual COM ports, as long as neither
port in the pair is currently part of a configured connection. To edit the port name, expand the
virtual port pair listing that contains the port you want to change. Double-click the port name, edit
the connection name, and press
ENTER
.
