3.2.2.2 Connection with a RTS/CTS handshake
It is possible to establish a connection through the RS232C interface with or without a handshake.
When operating an RS232C interface, a hardware handshake is used through the signals RTS and
CTS. These handshake signals must be operated by peripheral equipment.
If the employed peripheral equipment is operated with a DTR/DSR handshake instead of with the
RTS/CTS handshake as is here the case, these signals must be used to operate the serial interface’s
RTS/CTS pins.
