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. - RETURN TIMER TICK PARAMETERS
	AH = 07h
Return: AL = timer tick interrupt number
	AH = ticks per second on interrupt number in AL
	DX = approximate number of milliseconds per tick
SeeAlso: AH=16h
                                                                                

INT 14 - MultiDOS Plus IODRV - GET PORTIBM PC Portable (uses same BIOS as XT) STATUS
	AH = 07h
Return: CL = modem status (see #00305)
	CH = character at head of input queue (if any)
	DX = number of characters in input queue
Note:	the port number is stored at offset BEh in the Task Control Block
