/* 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.
