	AH = 00h
	AL = port parameters (see #00300)
	DX = port number (00h-03h) (04h-43h for Digiboard XAPCM232.SYS)
Return: AH = line status (see #00304)

	AL = modem status (see #00305)
Notes:	default handler is at F000h:E739h in IBM PC and 100% compatible BIOSes
	since the PCjr supports a maximum of 4800 bps, attempting to set 9600
	  bps will result in 4800 bps
	various network and serial-port drivers support the standard BIOS
	  functions with interrupt-driven I/O instead of the BIOS's polled I/O
	the 1993/04/08 Compaq system ROM uses only the low two bits of DX
	the default setting used by DOS (MS-DOS 6, DR-DOS 7.03, PTS-DOS) when
	  (re-)initializing the serial devices is AL=A3h (2400 bps, no parity,
	  1 stop bit, 8 data bits).
