RS - 232 DTE - DTE Communication Signalling














Lets us Assume that there  are two DTE and DTE lets say two computer as usually DTE devices are computers devices and the communication is done between them . Then Txd pin of the transmitter is connected to the RxD pin of Receiver and vice-versa. Similarly, the two ground terminal are connected to the ground and RTS (Request to sent ) of pin of transmitter is connected to the CTS (Clear to sent ) pin of the receiver and vice versa as shown in the figure , Similarly other handshaking signals are connected to the handshaking signals of the receiver.
