I am trying to attach a device to the serial port of a Mac which could be used as a replacement for the mouse. Talking to the device is simple. The problem I'm having is finding any information as to the location of the globals (?) or trap to use to update the mouse coordinates. Shoving a pseudo-mouse event into the queue doesn't work as that does not update the pointer location on the screen. I've searched IM and TN fairly thoroughly, but have found nothing. I would be grateful for any help, hints etc. Tony Jackson. Solbourne Computer tonyj@solbourne.com (303) 678-4342

I've posted bad Pascal code for this SetMouse routine in the past. Here's a Think C version: /* ------------------------- SetMouse ------------------------- */ /* some dangerous low-memory-global equates */ extern Point MTemp : 0x828; extern Point RawMouse : 0x82c; extern Point Mouse : 0x830; extern Byte MBState : 0x172; extern int CrsrNewCouple : 0x8ce; /* both New & Couple */ extern Byte CrsrNew : 0x8ce; extern Byte CrsrCouple : 0x8cf; #define Couple 0xff; /* value for CrsrCouple */ #define Uncouple 0x00; /* value for CrsrCouple */ void SetMouse(where) Point where; { long finalTicks; LocalToGlobal(&where); /* Get ready to store mouse position */ RawMouse = where; /* into RawMouse */ MTemp = where; /* and MTemp */ CrsrNewCouple = 0xffff; /* Hit CrsrNew & CrsrCouple */ Delay(5, &finalTicks); /* let the cursor catch up */ } /* SetMouse */ -- _______________________________________________________________________________ Chris Muir | "There is no language in our lungs {hplabs,pacbell,ucbvax,apple} | to tell the world just how we feel" !well!cbm | - A.
