Using Test Terminal
to Test a Port

Test Terminal (WCom2) allows you to open a port, send characters and commands
to the port, and toggle the control signals. This application can be used to
troubleshoot communications on a port-by-port basis.

The Send and Receive Test Data option sends data out the transmit line to the
loopback plug, which has the transmit and receive pins connected thus sending
the data back through the Rx line to Test Terminal, which then displays the
received data in the terminal window for that port. This test is only testing the Tx
and Rx signal lines and nothing else. A failure in this test will essentially prevent
the port from working in any manner.

The Loopback Test option tests all of the modem control signals such as RTS, DTR,
CTS, DSR, DCD, and RI along with the Tx and Rx signals.

Note: This test will fail and is expected to fail since RS-422 does not have the

modem control signals that are present in RS-232 for which this test is
designed.

The following procedure shows how to use Test Terminal to send and receive test
data to the serial ports and run a loopback test. If necessary, install the Comtrol
Utility package using

1.

Stop all applications that may be accessing the ports such as RRAS or any
faxing or production software. See the appropriate help systems or manuals
for instructions on stopping these services or applications.

If another application is controlling the port, then Test Terminal will be unable
to open the port and an error message will be shown.
