The telemetry string shown in the monitor is replaced with "Serial communications stopped" when the serial port is closed (by clicking Stop, Config or the program's close icon in the upper right). This was done to make it more apparent the telemetry has ceased rather than just looking like the telemetry is unchanging.
Removed extra line feeds from telemetry log file output.
The ability for the monitor to auto-recover from a USB cable unplug/re-plug event is temporarily broken as a result of the multi-threaded means of avoiding program hangs when the serial port is closed. I should have this fixed shortly.
