065: Restore Audio Routing Variable (Undo 037 and 038)
This command allows you to restore the audio routing within a macro to whatever it was at the
beginning of the macro. In other words, if commands 037 or 038 have been executed earlier in
the macro, their effects will be negated. It has no effect if used outside of a macro.
<065>
Example:
I want to make a macro to connect ports 1 and 2 and speak "Link Up" to whichever port entered
the command (which is the default, see command 050). This can be done without using
command 065 as follows:
055 500 ; erase whatever is in macro 500
056 500 036 292 507 ; speak "link up"
056 500 038 ; be quiet for the rest of this macro
056 500 000 12 ; connect ports 1 and 2
The above method may seem backwards, as the command to send the "link up" response comes
before the ports are actually connected. When the controller executes the macro, it puts the
words "link up" in a buffer to be spoken when the voice synthesizer has time and immediately
goes ahead and finishes the macro, connecting the ports. Assuming that the voice synthesizer is
not busy speaking something else, it will speak "link up" soon afterward.
The following macro does the exact same thing, and will sound exactly the same to the person
that enters it:
055 500 ; erase whatever is in macro 500
056 500 038 ; be quiet for the rest of this macro,
unless command 037 or 065 are
executed
056 500 000 12 ; connect ports 1 and 2
056 500 065 ; set the audio routing back to what it
was at the beginning of this macro
056 500 036 292 507 ; speak "link up"
Note that the ports are connected first, then the audio routing is restored and the message is
sent. It takes one more command in the macro (065) to put things in this order, but if it makes
more sense to you do program your macros this way, there is no harm in doing it. Note that in
both macros, command 038 is needed to keep the default response of command 000 from being
spoken: "one connect two".
