3. Build
-----------------------

1. Download, build and install libconfig C/C++ Configuration File Library 
   from http://www.hyperrealm.com/libconfig or use APT to install
   sudo apt-get install libconfig-dev
2. Set variable "BACNET_PORT" in library root directory Makefile to linux
3. Run "make clean all" from library root directory

-----------------------
4. Router configuration
-----------------------

4.1. Configuration file format.

//single line comment

/*
	multiline comment
*/

ports =
(
	//route_1
	{
		device_type = "<value>";
		//route specific arguments, see below
	},

	//route_2
	{
		device_type = "<value>";
		//route specific arguments, see below
	},

	//.....

	//route_n
	{
		device_type = "<value>";
		//route specific arguments, see below
	}
);

Note:	- arguments are separeted with ';'
	- routes are separeted with ','
	- no ',' after the last route

4.2. Configuration file arguments.

Common arguments:
	device_type	- Describes a type of route, may be "bip" (Etherent) or "mstp" (Serial port). Use quotes.
	device		- Connection device, for example "eth0" or "/dev/ttyS0"; default values: for BIP:"eth0", for MSTP: "/dev/ttyS0". Use quotes.
	network		- Network number [1..65534]. Do not use network number 65535, it is broadcast number; default begins from 1 to routes count.

bip arguments:
	port 		- bip UDP port; default port is 47808 (0xBAC0).

mstp arguments:
	mac		- MSTP MAC; default value is 127.
	max_master	- MSTP max master; default value is 127.
	max_frames	- 1. Segmentation does not supported.
	baud		- one from the list: 0, 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400; default baud is 9600
	parity		- one from the list (with quotes): "None", "Even", "Odd"; default parity "None". Use quotes.
	databits	- one from the list: 5, 6, 7, 8; default 8.
	stopbits	- 1 or 2; default 1.

4.3. Example of configuration file.

	ports =
	(
		{
			device_type = "bip";
			device = "eth0";
			port = 47808;
			network = 1;
		},
		{
			device_type = "bip";
			device = "eth1";
			port = 47808;
			network = 2;
		},
		{
			device_type = "bip";
			device = "eth1";
			port = 47809;
			network = 3;
		},
		{
			device_type = "mstp";
			device = "/dev/ttyS0";
			mac = 1;
			max_master = 127;
			max_frames = 1;
			baud = 38400;
			parity = "None";
			databits = 8;
			stopbits = 1;
			network = 4;
		}
	);
