Hi John,

Do you think this code will be thread safe?

While it is rare that multiple threads will access the keyboard it is
possible, especially with multiple VIO windows open from the same app.

Perhaps

 #define INCL_KBD
 #include 
 
 void setBinaryKbdMode(HKBD kb)
 {
   KBDINFO ki;

   ki.cb = sizeof(ki);
   KbdGetStatus(&ki, kb);

   ki.fsMask &= ~KEYBOARD_ASCII_MODE;
   ki.fsMask |= KEYBOARD_BINARY_MODE;
   ki.cb = sizeof(ki);
   KbdSetStatus(&ki, kb);
 }

would be a little safer. If you want it to manipulate the default
keyboard call it using a parameter of NULLSHANDLE or 0.

Regards

Dave
