Hardware handshaking: (RTS/CTS)
The RTS line is activated by the decoder before transmitting a character. Transmission is
possible only if the CTS line (controlled by the Host) is active.
Figure 23. RTS/CTS handshaking
Software handshaking: (XON/XOFF)
During transmission, if the Host sends the XOFF character (13 Hex), the decoder interrupts
the transmission with a maximum delay of one character and only resumes when the XON
character (11 Hex) is received.
