Re: Serial port programming in Visual Studio >Visual Basic> Windows form application
Sometimes the software package will include a sample program of what you want to do.
You may need to poke through folders labelled 'samples', 'examples', 'help', etc.
And deeper among folders such as 'communication', 'comm', 'serial', etc.
With the BASIC's I'm acquainted with, you open serial communications by using a command similar to "OPEN COMM" followed by a few parameters. After that you read or write to the serial port similar to the way you do a disk file.
