how can i modify this Initialize vi to allow me to assign a different com port?

[wb2nvy]

The attached VI is associated with a California Instruments programmable power supply. I need to set it up to work with the power supply connected through a 4 to 1 serial to USB hub, which shows up as com ports 14-17 in my Device Manager. Other Initialize VIs give me a drop down box with all com ports listed and I can select the one I want. This one doesn't give me any other options than GPIB and COM1. Can anyone suggest a way to modify this VI to accomplish this? I have a call into C.I. but don't know when they will respond and I'd like to pursue a parallel and more reliable course of action.

Hi wb2nvy,

you have to edit the combo box 'resource name'. Right-click, select 'Edit items', duplicate the entry 'Serial Port...' and change the copy to COM14 / ASRL14. Maybe this does the magic

But:
Your call is handled by a dll! Maybe this dll doesn't know how to handle ASRL14 and only allows the predefined strings in your combobox...
