  26         Set the console handler for the current process, and return the
  27         old handler.
  28
  29     INPUTS
  30         handler         - The new console handler for the process.
  31
  32     RESULT
  33         The address of the old handler.

  35     NOTES
  36         The use of Task in the name is because historically filesystem
  37         handlers were tasks (instead of Devices).
