input for expression in VISA find resource to detect RS-232 and RS-422 separately

[Vrks]

Hi All,

Does anyone know how to detect only RS-232 ports and only RS-422 ports using find resource or anyother way.

Depends on what you exactly want.

Maybe on of the serial property nodes can help

Or you can name each port with an alias  in MAX.

Hi ,

COM ports may be added or removed sometimes, so if i can find present available RS-232 ports and RS-422 and place it in seperate drop downs.
