DTE to DTE without Handshaking

There are several methods for wiring the RS-232 COM port to DTE (Data Terminal Equipment) and
DCE (Data Communications Equipment) devices. The simplest connection requires only 3 wires:
RxD, TxD and signal ground. The following diagram shows a common RS-232 COM port to DTE
device.

DTE to DTE with Handshaking

Some DTE devices may require hardware handshaking lines. The most common are the CTS and
RTS lines. Less common are the DTR and DCD lines. The controller does not require these lines.
Refer to the specifications of the external device for exact requirements

.
