Parameter Type Description
<socket_id> Number Socket identifier; used when changing the Direct Link settings.
The allowed range is 0-6
<character_trigger> Number Enhanced Direct Link character trigger, the value represents the ASCII code (in base
10) of the character to be used as character trigger. The allowed range is -1, 0-255, the
factory-programmed value is -1; -1 means trigger disabled
