 * The master side of the TTY is the emulator.

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