Verifying a Serial Port

Windows 3.x Verification Test

Perform the following steps to test your hardware:

1. Run the hardware diagnostic program serdiag that came with your NI serial driver software. serdiag verifies that your hardware is functioning properly and that the configuration of your board does not conflict with anything else in your system.

2. Be sure to disconnect all serial cables before running serdiag. To run serdiag, double-click on the serdiag icon in the NI Serial Software group.

3. If serdiag completes with no errors, your hardware is functioning properly. If it returns an error message, go to the Troubleshooting or FAQ sections.
