INT 16 - Microsoft Word internal - MICROSOFT WORD COOPERATION WITH TSR

	AX = 5500h
Return: AX = 4D53h ('MS') if keyboard TSR present
Notes:	during startup, Microsoft Word tries to communicate with any TSRs
	  that are present through this call.
	if the return is not 4D53h, Word installs its own INT 09 and INT 16
	  handlers; otherwise it assumes that the TSR will handle the keyboard
SeeAlso: AX=55FFh,INT 1A/AX=3601h
