avoid using the digit 'D' in any of the command names. For more information about command

names, see Chapter 5.

Unkey or Press 'D' to Execute:

After entering a command name and any other digits that command might require, you can tell the

controller to go ahead and execute the command in several ways. If you are entering the command

from a radio, you should normally just unkey. The controller will execute the command and speak

a voice message to tell you what it did (except for a few commands that don't have voice

messages). There may be times when the receiver's squech is too loose and is stuck open or when

someone sits on their mike when the controller won't be able to tell when you unkey. At those

times, you need another way to make the commands execute. That is the purpose of the "force-

execution" digit. It tells the controller to execute the command right away. It is normally set to the

digit 'D'. You should not use it when it is not necessary, because as soon as you release the 'D', the

controller will start speaking the command response, even if you haven't unkeyed yet, and you

won't hear the first few words of that response. When you are entering commands from a

computer or serial terminal, you can tell the controller to execute a command in two ways, either

by entering a 'D' or pressing the enter key. When entering commands from the reverse autopatch,

you can't unkey or press 'D' (on most phones), so there is another way, called "timed execution".

When timed execution is turned on, you can just enter a command and wait for a few seconds and

the controller will execute it. For more information about the force-execution digit and timed

execution, see command 078.
