End user selecting com ports

[RTSLVU]

I am new to using visa serial.

I have some code that on my dev-station the front pannel drop down box gives you selections like Com1 Com2.

When I compile and build this the end user sees ASRL-1::INSTR and ASRL-2::INSTR.

End users find this very confusing.

Also what is the best way to have an end user select a com port and  make sure it is a valid selection without causing errors that abort the program?

Using the visa resource control with filtering (filter com ports) allows the user to select only valid ports.  I like to capture value change events and probe the device (a query command) to validate the device is connected and working.
