Note on Flow Control. XON/XOFF is a software-based flow control method,
using standard ASCII control characters to pause or resume data transmission.
RTS/CTS pacing, a hardware-based method, uses an electrical signal. Signals
are exchanged as follows:
RECEIVER RECEIVER RECEIVER RECEIVER RECEIVER TRANSMITTER TRANSMITTER TRANSMITTER TRANSMITTER TRANSMITTER
CTS ON ======> START SENDING
CTS ON <====== RTS ON (ready to send)
CTS OFF ======> RTS OFF (stop sending)
