Troubleshooting and Technical Support

This section contains troubleshooting information for your Comtrol device. You

should review the following subsections before calling Technical Support because

they will request that you perform many of the procedures or verifications before

they will be able to help you diagnose the problem.

Troubleshooting

If you are having trouble with a RocketPort or RocketModem, try the following.

Note: Most customer problems reported to Technical Support

are traced to cabling

or network problems.

1. Verify that you are using the correct types of cables in the correct places and

that all cables are tightly connected.

2. If you have an ISA adapter, make sure that you set the I/O DIP switch

correctly.

3. Enable the Verbose Event Log feature under the Setup Options tab and then

reboot the system.

4. Verify that you are addressing the port correctly. In many applications, device

names above COM9 require the prefix \\.\ to be recognized. For example, to

reference COM20, use \\.\COM20 as the file or port name.

5. Use the Test Terminal

program (wcom32.exe) to troubleshoot communications

on a port-by-port basis.

6. Use the Port Monitor

program (portmon.exe) to check for errors, modem

control, and status signals. In addition, it provides you with raw byte input

and output counts.

7. Use the Peer Tracer

program (peer.exe) to trace driver events.

8. Remove

and reinstall the driver.
