		THE AUTO DIALER

	The automatic dialer allows the computer to
dial the 493-5505 dataphone.  The number is dialed
by first doing a CONI to find out if the phone is
busy, then doing a CONO to set up things, and then
a DATAO of the number.  The dialer interface will
interupt when it thinks something happened that you
should know about, such as the number you dialed
answered, or it didn't.  The format of the instructions
is as follows:

The following is a brief description of what each of the bits means.

DSS	DATA SET STATUS
	When this bit is on, it means that you have reached a Dataphone
	snd are connected to it.
DSS←1	DATA SET STATUS went on.
	This means a Dataphone answered.  This bit also comes on immediately
	after a VOICE call has finished dialing.
DSS←0	DATA SET STATUS went off.
	This means the Dataphone you called hung up. You should
	do likewise.
DLO	DATA LINE OCCUPIED
	The dialer or its Dataphone is being used.
¬ACR	NOT ABANDON CALL AND RETRY
	After the number is dialed, if a Dataphone has not answered
	within 15 seconds, this bit goes off.  It is a suggestion
	that you hang up and try again later.  It has no effect on
	the call.
VOICE	VOICE MODE
	When this bit is set, the dialer will dial the call and then
	transfer the line to the A/D and D/A converters (this feature
	is not fully implemented as yet).
¬PWI	NOT POWER INDICATION
	Bit is on when there is no power to the dialer.  Good for
	disabling outgoing calls.
HANG UP
	Sure enough, it hangs up a dialer initiated call.
INTERRUPT
	Dialer is interrupting for some reason.  Possible reasons are
	DSS←1, DSS←0, ACR, attempting to dial with DLO, ¬PWI.
CLEAR INTERRUPT
	Clears interrupt.  An interrupt will occur when there is any
	significant change in status.
INTERRUPT ENABLE
	Enables dialer to interrupt when interrupt bit is on.
PI33-PI35
	PI channel
AREA
	This bit requires an Area Code to be dialed.  Calls to the 415
	dialing area must not have an Area Code.
