How to test com port is open in qb64

by Docfxit (no login)

Thanks for the information.

Sorry I wasn't clear enough.

When the code gets to the Open Com1: statement and fails, the On Error statement doesn't get triggered in qb64. So what I am looking for is a programmatic way to see if the the Open Com1: was successful or failed.

Thanks,

Docfxit
