INT 14 - MBBIOS - INITIALIZE PORT
AH = 00h
AL = port parameters
bits 7-5 data rate
(normally 110,150,300,600,1200,2400,4800,9600 bps;
9600,14400,19200,28800,38400,57600,115200,330400 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)
