-/* md_control_keyboard():
- *
- * This routine is much like md_cbreak_no_echo_nonl() below. It sets up the
- * keyboard for appropriate input. Specifically, it prevents the tty driver
- * from stealing characters. For example, ^Y is needed as a command
- * character, but the tty driver intercepts it for another purpose. Any
- * such behavior should be stopped. This routine could be avoided if
- * we used RAW mode instead of CBREAK. But RAW mode does not allow the
- * generation of keyboard signals, which the program uses.
- *
- * The parameter 'mode' when true, indicates that the keyboard should
- * be set up to play rogue. When false, it should be restored if
- * necessary.
- *
- * This routine is not strictly necessary and may be stubbed. This may
- * cause certain command characters to be unavailable.
