Finding how many COM ports on the computer

[nqn827]

Hi,

Is there any function(s) in LabWindows/CVI 8.5 that I can call to find out how many COM ports are on the sysem, and what the port numbers are?

TIA

Just look at the following registry key: HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM

It lists all available serial ports in the system and their names.

You cal use functions int the programmer's toolbox to read registry keys.
