Programatically Changing Com Ports

[ReevesJA]

I need to programatically change the COM port within LabView.

I am writing a program for clients and need to save the COM port settings within an exicutable. I was going to atchieve this by writing to an ini file. I cannot directly save the VISA variable but can save the following properties.

Intf Inst Name

Intf Type

Intf  Num

The problem is I cannot write to these properties on the initialization state of the program. Is there a way I can save which COM port was being used from one session to another of an exe? Thanks in advance for all your help.

Hi Jesse,

you can store it as a string. If you read the string from a file you can directly connect it as a com port selection. It also works if you typecast the string to the com Port type.
