Assignment as an RS-232:
DCD Data Carrier Detect. RCV channel used, for example, by a
connected modem to inform the PC that it is receiving a carrier
signal (active connection).
RX Receive Data. Line on which data is received.
TX Transmit Data. Line on which data is transmitted to a
peripheral device.
DTR Data Terminal Ready. XMIT channel used by the PC to signal
to a connected peripheral device that its interface is switched
on and initialized.
DSR Data Set Ready. RCV channel used by the connected periph-
eral device to inform the PC that it is switched on and inilital-
ized.
GND Signal Ground
