SOFT Software handshake (XON, XOFF)
The communication is controlled with the control codes (XON, XOFF).
Sure communication can be performed even with the cable connected to
TxD, RxD, and GND only. However, binary data cannot be transferred.
Also, effective speed may be lowered.
HARD Hardware handshake (RTS, CTS)
The communication is controlled with hardware control wires (RTS,
CTS).
Perform the EXIT operation to return to one-previous menu.
If the handshake is set, the result is displayed for a moment, and one-previous menu comes
back.
If the handshake is enabled, the transmission is suspended when the reception buffer
becomes almost full, and it restarts when a space is made in the reception buffer.
