INT 61 - Banyan VINES - TALKPORT SERVICE - INTERCEPT VINES 25th-LINE MESSAGES   
	AX = 0008h
	BX = 0003h
	DS:DX -> request block (see #03442)
Return: AX = status
	    0000h successful
	    0001h network software not installed or incompatible
Notes:	message handler should not call 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. or DOS functions, and should
	  either call next handler or simply return
	to stop intercepting messages, set prev and next request blocks to
	  point at each other
