RTS- Request to Send, DTE requests DCE to become ready to accept the data.ĬTS- Clear to Send, DCE acknowledges DTE that I am ready to receive the data. RI- Signal from DCE to DTE, Modem (DCE) detects ring from line. TD- Transmit data, it carries data from DTE to DCE.ĬD- Carrier Detect, signal from DCE to DTE. For example, DTE is the computer and DCE is the modem connected to the telephone line. RD- Receive data, it receives data from DCE (Data communication Equipment) and pass to DTE (Data Terminal Equipment). The interface is mainly used for one to one serial communication forĮxample computer to dial up modem connection.įigure-1 depicts RS232 pin diagrams for DB9 connector.įigure 2 depicts RS232 pin diagrams for DB25 connector.Īs shown in the figure, it carries both data and control signal lines.
