Pre-release testing serial port emulation (MacOS only)

This pre-release tests a low level hardware emulation of the external serial port. Try this out by downloading the corresponding version of NCX from GitHub:

https://github.com/MatthiasWM/newton-connection/releases/tag/mv0.1

Just launch NCX and Einstein on the same machine. Then start the docking app on the emulated Newton and connect via the default "Serial" setting. Einstein's Newton should connect to NCX within 5 seconds.
