RTS: It is an output signal which is used to set the status RTS.

CTS: It is an input signal which controls the data transmit circuit.

DTR: Data terminal Ready is an output signal.

DSR: Data Set Ready signal is an input signal.

The following are active-low pins of Modem.

Modem control (modulator/demodulator) РІР‚вЂњР”Р„ device converts analog signals to digital signals and vice-versa and helps the computers to communicate over telephone lines or cable wires.

In this way, this unit selects one of the three registers- data buffer register, control register, status register. The operation selection depends upon input signals as: It controls the overall working by selecting the operation to be done. It is a control block for overall device.
