> 1.10.1 | Software Flow Control (XON/OFF Handshake)

> Software flow control can be used to control the data flow in both directions from DTE to TC65 and from TC65 to DTE. Software flow control uses different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data flow. Hence, all data that represent XON or XOFF characters will be interpreted as control characters. This applies also to characters included within the data stream to be transmitted (usually plain ASCII text files do not inlude such characters). The only advantage of software flow control is that three wires would be sufficient on the serial interface.
