// Operating in software serial full duplex mode, runs at 19200bps and few errors (~2.5%).
// Operating in software serial half duplex mode (both loopback and repeater),
// runs at 57600bps with nearly no errors.
// Operating loopback in full duplex, and repeater in half duplex, runs at 38400bps with nearly no errors.
