Comtrol Tools
This section discusses the following utilities that are installed with most Comtrol
drivers for Microsoft operating systems:
• Test Terminal program (wcom32.exe), which can be used to troubleshoot
communications on a port-by-port basis (
Using Test Terminal on Page 69).
• Port Monitor program (portmon.exe), which checks for errors, modem control,
and status signals (
Using Port Monitor on Page 71). In addition, it provides
you with raw byte input and output counts.
• Peer Tracer program (peer.exe), which traces driver events ( Using Peer Tracer
on Page 77).
• FreePort program, which frees a specified port ( Using Freeport on Page 78)
Using Test Terminal
WCOM32 is a terminal program that enables you to open a port, send characters
and commands to the port, and toggle the control signals.
Note: WCOM32 will not work on ports used by RAS if Remote Access Service is
running or any other application is using the port. If you are using RAS,
you must stop the service before starting WCOM32 to test RAS COM ports.
To test ports that are not used by RAS, you do not need to stop RAS.
Follow these steps:
1. Start Test Terminal from the Comtrol NS-Link program group.
2. Select Ok if this screen appears:
3. Select Open Port from the Port menu. A list of possible COM port numbers
displays.
4. Select the COM port you want to test.
