INT 15 - TopViewTopView, DESQview, TaskView, OmniView, other compatibles - SEND MESSAGE - "REDRAW" - REDRAW WINDOW
	AH = 12h
	BH = 13h
	BL = window object
	    00h DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. on top of stack is handle for window to redraw
	    01h redraw task's default window
	    0Ch (DV 2.26+) redraw window of task owning handle on top of stack
	    0Dh (DV 2.26+) redraw default window of parent of current task
Return: STACK popped if handle was passed on stack

INT 15 - DESQview 2.50+ - SEND MESSAGE - "READINTO" - GET NEXT MAIL MESSAGE
	AH = 12h
	BH = 13h
	BL = mailbox from which to read
	    00h DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. on top of stack is mailbox handle
	    02h use given task's mailbox (task's handle on top of stack)
	    03h use current task's default mailbox
	STACK: DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. size of buffer in bytes
	       DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. pointer to buffer
Return: STACK: DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. number of bytes read
Program: DESQview 2.5x is distributed as part of DESQview/X 1.0x
Notes:	this call blocks if no input is available, but will return less than
	  the requested number of bytes if some (but insufficient) data is
	  available
	use this call instead of AH=12h/BH=04h if the mailbox has flag bits
	  4 or 5 set, as common memory may be exhausted by that call when
	  attempting to read the next message
