View source for Toggle Applications

This article describes different application where the common scenario is to toggle a feature on/off using just a DAK key. Some features have additional options that gives additional opportunities.

In the examples below the AlphaCom data commands used are hyperlinked. Common for many of them is:
: [[$WUDD]]
: 

The [[Station DAK key as RCI (Event Type)|DAK as RCI]] event is the preferred event for most of the applications.

==Conversation==
Toggle between Call and Cancel: pressing DAK key 1 sets up a call to station 101. Second press cancels the call. A second event must be created to handle the scenario where 101 initiates the call , or ends the call.

Action commands:
 IF %udd(%1.phy)
 $C L%1.dir
 WUDD %1.phy 0
 STOP
 ENDIF
 $CALL L%1.dir L101
 WUDD %1.phy 1

[[File:Toggle Applications 8.PNG|thumb|left|500px|Adjust UDD if call initiated or ended from the other station]]
<br style="clear:both;" />

Action command:
 WUDD %1.phy %chg(1,0)

The same DAK can also answer an incoming call in private mode. Then the following event must be added:

<br style="clear:both;" />

In addition these commands must be added to the top of the initial DAK as RCI event:
 IF %op(%udd(%1.phy),=,2)
 $M L%1.dir
 pause
 $MREL L%1.dir
 WUDD %1.phy 1
 STOP
 ENDIF

For more details see [[$CALL]], [[$C]], [[$M]], [[$MREL]] and [[PAUSE|pause]]

==Call Request==
Toggle between Call Request and Cancel Call Request: Pressing the DAK key the first time sends a Call Request to station 101 in the example. Second press cancels the call request. A second event must be created to handle the scenario where 101 answers the call request, or cancels it.
