    I had to google for the Linux devices - apparently these are old designations!

    Answer Time:

    1. COM 1 B. IRQ 4 I /dev/ttyS0
    2. COM 2 A. IRQ 3 II /dev/ttyS1
    3. COM 3 B. IRQ 4 III /dev/ttyS2
    4. COM 4 A. IRQ 3 IV /dev/ttyS3

    What windows calls a COM port, Linux considers a tty or serial port. Since Linux handles *everything* as part of the file structure, COM 1 becomes /dev/ttyS0. If you know your basic A+ material on which COM ports match which IRQs, the rest is easy.
