VISA resource name-COM ports

[mnx]

Is there any setting for VISA resource name so as to configure it to display a list of only COM ports and not any other serial ports like LPT or GPIO INTFC?

Hi mnx,

you can use VISAFindResource to get a filtered list of VISA resource names, it's context help describes all parameters...

I use "ASRL[0-9]*::?*INSTR" to filter COM ports.

I was planning to do something with VISA resource name as with VISA find resource I need to keep on checking dynamically if user has plugged in any USB-serial converter on the fly and that will increase code complexity a bit..Also, I want to display ports as "COMx" rather than their addresses "ARSL.."

Anyways, I am planning to implement the following code:

Just wanted to confirm if something of this sort is possible with VISA resource name settings?
