Troubleshooting
Comtrol ships a test terminal program (WCOM32.EXE) with RocketPort USB Serial and Modem Hub. Please
see the following discussions for information on testing your hub.
If you are having problems, use the following procedure:
1.
For serial hubs, verify that you are using the correct types of serial cables. See the
RocketPort USB Serial
Hub Hardware documentation
for pin out information.
2.
For Modem Hubs, try manually resetting the inactive modem.
3.
Verify that all cables are connected securely.
4.
Reboot the Windows 98 machine.
5.
Verify that you are addressing the port correctly. In many applications, the device names above COM9
require the prefix \\.\ in order to be recognized. For example, to reference COM10, use \\.\COM10 as the
file or port name.
6.
Use the Test Terminal program (WCOM32) to troubleshoot communications on a port-by-port basis.
