RTS - Request to Send
DSR - Data Set Ready
DCD - Received Line Signal Detector
CTS - Clear to Send
DTR - Data Terminal Ready
These handshaking signals are similar to the ones you have on serial com port communication between PCs.

For example, RTS, CTS are used for hardware flowcontrol.
Devices are of two types, DTE and DCE device. DCE devices are typically switches, hubs etc, while router are usually DTE type interface. So the DCE can use CTS to slow down the rate of DTE.

Hi,
Please find some info below
Clear To Send (CTS) pin 5
The CTS is an input signal. This means that it waits for a signal of the connected device.
When the connected device receives the RTS-signal and it opened to receive data, it returns a signal back. This is the CTS-signal for the initial computer

RTS Request To Send DTE output, DTE would like to transmit
CTS Clear To Send DTE input, DCE is ready to transmit
DSR Data Set Ready DTE input, DCE is ready to communicate
DCD Data Carrier Detect DTE input, data link established, also known as Receive Line Signal Detect (RLSD)
DTR Data Terminal Ready DTE output, device ready
