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. - READ BLOCK
	AH = 18h
	CX = maximum number of characters to transfer
	DX = port number
	ES:DI -> user buffer
Return: AX = number of characters transferred

INT 14 - Digiboard DigiCHANNEL PCIBM PC/X* - SEND BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. COMMAND
	AH = 18h
	ES:BX -> 16-byte command string
	DX = port number (00h-03h) (04h-43h for XAPCM232.SYS)
Return: AH = status
	    00h successful
	    80h timeout
	AL = mailbox status
	    00h no errors

The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. error
	ES:BX buffer filled in with mailbox string
	ZF clear if no errors
	ZF set if either status byte contains an error code
