programatically determine port and COM mapping

[SriVidya]

Hello all,

Please let me know the method of programatically determining the port and COMx mapping using labwindows CVI. I mean to ask which port referes to which COM or which resource(like ASRL1). I am using NI PCI 8433 card.

Thanks in advance.

Hi,

using the Search function of this forum (e.g. serial port) will uncover the following thread with a nice code by msaxon:
