/*
	DSR (device service routine) emulation.  All devices that
	conform to the TI standard file API have hardware
	emulation (through CRU traps) and possibly software
	emulation (through the DSR routine).
	
	The way to add a new DSR is:  (1) make a new CRU module
	for the I/O address space (like >1200...>12FF).  The handler
	for SBO >0 should turn on the ROM for the DSR at >4000 and
	update currentdsr.  See examples.  (2) possibly add a handler
