Assignement as RS-232:
DCD Data Carrier Detect; receiving line, on which for in-
stance a connected device informs the rho4.0 that it
is receiving a carrier signal (existing connection).
RXD Receive Data; Data receiving line
TXD Transmit Data; Data transmitting line to the
peripheral equipment
DTR Data Terminal Ready; transmitting line, on which the
rho4.0 informs a connected peripheral device that
its interface is switched on and initialized.
