  19  * The master side of the TTY is the emulator.
  20  *
  21  * The slave side is where a client process can write output and can read
  22  * input. For this purpose, it must open the file (terminal device) whose
  23  * name is returned by @ref slaveTTY for both reading and writing. To
  24  * establish the stdin, stdout, and stderr channels the file descriptor
  25  * obtained by this must be dup'd to file descriptors 0, 1, and 2, resp.
