   AH = 00h
   AL = port parameters
       bits 7-5 data rate
           (normally 110,150,300,600,1200,2400,4800,9600 bps;

           if the high-speed option is set)
       bits 4-3 parity (00 or 10 = none, 01 = odd, 11 = even)
       bit 2    stop bits (set = 2, clear = 1)
       bits 1-0 data bits (00 = 5, 01 = 6, 10 = 7, 11 = 8)
   DX = port number

Return: AH = line status (see AH=03h)
   AL = modem status (see AH=03h)
