- ; First we need to set the drvrFlags (IM II-188), choose from
- ;
- ; dReadEnable enable driver for read operations (drivers only)
- ; dWritEnable enable driver for writing (drivers only)
- ; dCtlEnable enable driver/da for control operations
- ; dStatEnable enable driver/da for status operations (drivers only)
- ; dNeedGoodBye driver/da needs a "goodbye kiss"
- ; dNeedTime driver/da needs "main thread" time
- ; dNeedLock driver will be accessed at interrupt level (drivers only)
- ;
- DC.B (1<<dCtlEnable) + (1<<dNeedTime) ; periodic, control flags set
- DC.B 0 ; Lower byte is unused
- ;
- ; Next is the the drvrDelay (IM II-188), set only if dNeedTime flag set above
- ;
- DC.W 5*60 ; 5 sec periodic update

- ; Next is the the drvrEMask (IM I-444), which events DA can respond to...
- ; Must be NIL for drivers, for DA's choose from
- ; mButDwnEvt mouse button down is event 1
