Hello Matt?

are all of the virtual COM ports identical in function in this latest QMX firmware?? Meaning can any of the three be used for any supported function on the QMX by an application?? Or is it like some radios (looking at you, Yaesu) where the different virtual COM ports support different functions/capabilities from one-another.

I have never owned nor any radio transceiver other than homebrew and QRP Labs radios. So I mostly have no idea what they do.

But yes, in QMX, all three Virtual COM ports are completely identical. In all cases, the supported functions are currently CAT and Terminal. Any Virtual COM port is assumed to be a CAT interface, unless a carriage return or line feed character is received, in which case it becomes a Terminal. No CAT commands ever include carriage return or line feed characters which is why this works. Choosing "Exit Terminal" from the main menu before closing your terminal emulator returns a COM port to the CAT function.?
