Generic_Serial_Device (also knowk as GSD) is a Pluto device that allows enduser to do simple programming for RS232, serial USB or network connected devices.

Short description

It's a standard DCE device, it only can execute commands and send events (no event handler yet, but Aaron wants it badly).

The main idea is instead of programming a device in C++, compile, link whith proper libraries you can edit (in a webpage) few lines of code in ruby which will be executed when device receives that command. It exports several objects into ruby so you'll have access to devicedata, device hierarchy, established connection and so on.

The ruby code for each device template is storred somewhere in InfraredGroup_Command table. To edit infrared code, on pluto-admin website go to Wizard> Devices > Generic_Serial_Devices. You have to add a device from a device template in order to see anything in that page.

Select the device, and click "RubyCodes" button to be able to edit code that will be executed. You should be able to see commands that are specified in device template (like ON/OFF/WhateverElse) and a group of Internal commands (Private_Method_Listing, Process_IDLE, Process_Incoming_Data, Process_Initialize, Process_Receive_Command_For_Child and Process_Release).
