But that format (used only on the original TAPR Mic-E's) has been more or less broken by the re-use of those two special ' and ` markers for all future Mic-E TYPE codes. The good news is that all EXISTING code that parsed those old units telemetery WILL CONTINUE TO WORK. Its just that they will get confused by newer devices and so it is not a good idea to continue to encourage that telemetry format's use. Something like that.
