INT 14 - FOSSIL(Fido/Opus/Seadog Standard Interface Layer)  A standardized API for performing serial I/O, originally used by the Fido and Opus bulletin- board software and Seadog bulletin-board mailer, but now in wider use. - RAISE/LOWER DTR
	AH = 06h
	DX = port
	AL = DTR state to be set
	    00h = lower
	    01h = raise
Return: nothing
SeeAlso: AH=05h"MBBIOS",AH=1Ah
                                                                                

INT 14 - MultiDOS Plus IODRV - WRITE CHARACTER TO PORTIBM PC Portable (uses same BIOS as XT)
	AH = 06h
	AL = character
Return: AL = status
	    00h successful
Notes:	the port number is stored at offset BEh in the Task Control Block
	if output queue is full, the calling task is blocked until the
	  character can be stored
