Int 2F Fn DE0A  C - Desqview V2.26+ External Dev Interface - Change Keybo  [Q]

   AX = DE0Ah
   BX = mapping context of task receiving focus
   DX = handle of running task

Notes: driver should pass this call to previous handler before processing it
   this call often occurs inside a keyboard interrupt
   DV 2.42 does not provide this call to XDI handlers running inside a
     window; instead, it directly calls the INT 2F handler which was
     active at the time DV started
