Special Command Prefixes¶

Special command prefixes, added in Composer 2.0, allow the programmer to temporarily enable the echo mode, verbose mode, or quiet mode for that particular command. The $v prefix is helpful when running in Quiet mode and executing the V command.

$e (Echo Mode)

The $e prefix will execute the command and echo back the command that was sent This can be helpful when correlating a response to the commands that generated it.

The echoed command will be enclosed in {curly brackets}.

As an example:

$e CS 140 65535\

Causes the following acknowledgement

{CS 140 65535} ACK

$v (Verbose Mode)

The $v prefix will execute the command as if quiet mode was turned off for the duration of the command.

As an example:

$v SSYSS 1.1004.0.3.0=14257787728 \

will return the string

>Set System String '1.1004.0.3.0' to '14257787728' succeeded>

As another example:

GSYSS 1.1001.11.3.0 \

could return the string

Conference Room

$v GSYSS 1.1001.11.3.0 \

could return the string

>System String '1.1001.11.3.0' is 'Conference Room'>

$q (Quiet Mode)

The $q prefix will execute the command as if quiet mode was turned on for the duration of the command regardless of the state of quiet mode.

As an example:

$q SSYSS 1.1004.0.3.0=14257787728

Will return the string

ACK
