PCBCN - For controlling a timed personal beacon using a PC. Specifiy the timing repeat interval, offset from the hour in minutes and seconds and the Tx duration in seconds. At the right time, the DTR and RTS lines of the requested COM port will repeatedly activate a beacon transmitter for the duration.
How we can use modern technology to make beacons more useful, add versatility and ease
the approval / licensing issues.
