There are a select number of SEND_COMMANDs recognized by the Metreau Entry Communicators.
SEND_COMMANDs
Below is a list of SEND_COMMANDs supported by the Metreau Entry Communicators from NetLinx
masters.
To use these commands, establish a Telnet session from the PC to the NetLinx master. Additionally, you
could use NetLinx Studio 2.4 or the master’s web page to send the commands.
Touch Panel Intercom Commands
These commands are used to setup connections between panels that are Intercom-enabled. The "
^MOD

All text is based on a Unicode index.
Some (not all) G4 Touch Panels feature hardware to support intercom functionality.
Only Touch Panels that support intercom may be able use intercom with the Metreau
Entry Communicators.
