FBIOS is a COM port handler that is configured with command line
specifications for interrupt, hardware type, and port addresses.
The command line contains groups of specifications delimited by blanks.
FBIOS spec1 spec2 spec3 etc.
Each specification has several fields, delimited by commas.
The first field is a single number giving the IRQ: 2,3,4 or 5
The second field is a single letter giving the hardware type:
C - Standard type COM port, no shared interrupt.
Q - QuadRAM Quadport board.
S - Shared interrupt board (modified MS-400)
