the Receiver-Controlled RTS/CTS Handshaking Mode
H.1.2 Transmitter-Controlled RTS/CTS Handshaking
In this mode, the Transmitter now has the ability to negate the RTS output (to the Receiving Device). Specifically, this
mode allows the Transmitter to negatye the RTS signal, one bit period after emptying the THR and TSR.
