Opening Ports The following procedure shows how to use Test Terminal to send and receive test
data to the serial ports. If necessary, use
Installing PortVision DX on Page 37,
which contains Test Terminal.
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.
2. Start Test Terminal (WCom2). If necessary, start PortVision DX from the Start
menu, select Programs > Comtrol > PortVision DX > PortVision DX or click the
desktop shortcut.
3. Select Tools > Applications > Test Terminal (WCom2).
4. Select File > Open Port, the appropriate
port (or ports) from the Open Ports
drop list and Ok.
Note: If you left Port Monitor open
from the previous subsection,
you should show that the port is
open.

and receive test data.
