  28         Set the console handler for the current process, and return the
  29         old handler.
  30
  31     INPUTS
  32         handler         - The new console handler for the process.
  33
  34     RESULT
  35         The address of the old handler.
  36
  37     NOTES
  38         The use of Task in the name is because historically filesystem
  39         handlers were tasks (instead of Devices).
