Despite all the good comments here by other skilled people I'd recommend to
determine whether the transmission line to the devices accessed support full
My knowledge is a bit rusty on this topic. But I vaguely remember having to
deal with symmetric two-wire connections (RS-485) which were definitely
limited to half-duplex by the wire. So the PC hardware was a normal serial
port with the usual UART hardware device but the transmission protocols were
limited to half-duplex.
