The ADS program (run by "R ADS" monitor command) will issue the ADSMAP UUO
to control your audio switch selection.  It is intended mainly for debugging
the UUO; anything you really want to do to your audio switch setting can be
more easily done with the various versions of ESC U and ESC B.  ADS can also
tell you the audio switch setting for a particular terminal, or which terminals
have a particular audio channel selected.  The following text is typed out if
you type "?" to ADS:

COMMANDS CONSIST OF THE FOLLOWING FIELDS, OPTIONALLY AND IN ANY ORDER:

CHANNEL TO SELECT:
	<OCTAL INTEGER>

TEMPORARY/PERMANENT FLAG, AND DURATION IF TEMPORARY:
	<NOTHING> | T [ <DECIMAL INTEGER> [ . <DIGIT 0-3> ] ]

	NOTHING FOR PERMANENT MAP.  T WITH NO DURATION IS INFINITE.
	DURATION IS IN SECONDS AND OPTIONAL QUARTERS, E.G., 5.2 IS 5 1/2 SECS.

PAGING DISPOSITION:
	P0 | PI | <NOTHING>		INTERRUPTABLE
	P1 | PN				NOT INTERRUPTABLE
	P2 | PE				INTERRUPT AND EXTEND DURATION

BEEP DISPOSITION:
	B0 | BI | <NOTHING>		INTERRUPTABLE
	B1 | BN				NOT INTERRUPTABLE
	B2 | BE				INTERRUPT AND EXTEND DURATION
	B3 | BD				DELAY BEEP

HOW TO DEAL WITH PRE-EXISTING TEMP MAP:
	<NOTHING>			WAIT FOR OLD TEMP TO FINISH
	Z				ZAP OLD TEMP, DO THIS ONE NOW
	I				IGNORE THIS UUO IF ∃ OLD TEMP

WHAT TO DO AFTER THIS UUO:
	<NOTHING>			WAIT FOR NEW TEMP TO EXPIRE
	R				RETURN WITHOUT WAITING

+ WILL RESET YOU TO PERMANENT MAP.
<CR> WITH NO COMMAND DOES A BEEP TO YOUR TERMINAL.

<ALT> TYPES YOUR PERMANENT AND TEMPORARY MAPS.  IN THIS TYPEOUT:

	(PAGE)	  __\	THERE IS A PAGE IN PROGRESS WHICH YOU'RE MISSING
	(*BEEP*)    /	YOU ARE BEING BEEPED NOW
	(BEEP)		YOU WILL BE BEEPED WHEN YOUR TEMP RUNS OUT
