The io-adresses of the serial ports found by the bios are stored starting 
0x0040:0x0000 (segment:offset), the printer-ports starting at 0x0040:0x0008 in 
physical (DOS) memory. Use some of the dosmemget or farpeek-functions to access this 
locations. Each adress is stored as 16 bit int. Use 'debug' 'd40:0' to take a look 
what your bios has found.
