Steve Passe adc91a77c1 Created a private simple_lock to control accesses to com data structs ... and hardware. There is now another simple_lock around clock data/hardware accesses in clock.c and microtime.s. It is my belief that this is the only area sio/cy might stumble into during an unblocked INTerrupt. Thus I separated the sio/cy code from the generic disable_intr()/enable_intr() routines. Controlled by smptests.h: USE_COMLOCK, ON by default.		1997-08-31 03:17:18 +00:00
