INT 14 - Connection Manager - SEND CHARACTER                                    
	AH = 01h
	DX = FFFFh
	BH = character to send
Return: AH = return code (00h-02h,06h) (see #00303)
Notes:	if DX is 0-3 on entry, Connection Manager emulates the standard 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.
	  function, but redirects the port over the network; if DX is any other
	  value, the call is chained
	this function is provided primarily for compatibility; AH=06h/DX=FFFFh
	  is the preferred function because it provides better performance
