Hi QRZers; Ever found needing to have more than one app using the serial port - and you got bummed? Like, you doing some digital mode and logging with N1MM? Or <insert other simultaneous need here>? And not wanting to pursue the HRD share route? I have written a tutorial on how to setup Eterlogic VSPE - it will create a new COM port to be used by your applications- and this can be shared / used simultaneously by more than one application.
