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 duplex. 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.
