6.1.9 Handshake
Handshake controls the data flow at the serial interface if the data rate is higher than
what the device or the connected terminal device can currently process.

Note
You must deactivate handshake of the serial interface in the follow-
ing cases:
You must deactivate handshake of the serial interface in the follow-
ing cases:
The device is operated as a stand-alone device, i.e. it is not
connected via the serial interface.
The device is operated at a device which does not support
hardware handshake.
No handshake
The device ignores redundant data.
Software handshake
The device controls the data flow with the help of control characters (XON/XOFF) via the
data lines.
The device ignores redundant data.
