Comtrol Utility The Comtrol Utility is available on the Software and Documentation CD or you
can
download (Page 6) the latest version. The file is a self-extracting zip file that
automatically starts the installation procedure. It is not necessary to reboot the
PC after installation.
The Comtrol Utility package includes the following applications that you can access
from the Comtrol Program group:
• Port Monitor (PortMon2) checks for errors, modem control, and status signals.
In addition, it provides you with raw byte input, output counts, and confirm
that the device driver is functioning. It can determine if the ports are in use by
another application.
• Test Terminal (WCOM2) can be used to troubleshoot communications on a port-
by-port basis (
Using Test Terminal to Test a Port on Page 21). Test Terminal
requires a loopback plug. You can build a loopback plug if you are missing the
loopback plug shipped with the adapter (
Connecting RS-422 Serial Devices on
