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.
