Larry -
I assume you're running the nano-X API. The GdReadMouse routine
is called in nanox/srvevents.c to queue up events from the lower level
driver into the nano-X event queue. grep that file and put some debug
statements in the routine that calls devmouse.c::GdReadMouse()
and queues the events for the nano-X application. IIRC this routine
is something like GsMouseEvent. The GsMouseEvent routine is
called from the upper level main loop in nanox/srvmain.c::GsSelect()
when it is notified that there is new mouse data. GsMouseEvent
then calls GdReadMouse and the mou_touchscreen driver entry point.
Regards,
Greg
