The RTS232 and CTS232 signals control data transmission and synchronize
the connected devices.
If the RTS/CTS handshaking protocol is enabled, the DS4300 activates the
RTS232 output to indicate a message is to be transmitted. The receiving unit
activates the CTS232 input to enable the transmission.
