gnuart - the UART erlang application

======

Compile the application and build the shared object

	$ make all

Before start application, you must configure priv/gnuart.uart file. This file is the configuration where 

the devname must be set. The order of the specs is:

	devname minimun_time maximum_time timeout

The specs can be changed at the runtime and could be reloaded when write data to devname.

Start the application with the code loaded 

	$ erl -pa ebin/

	

	1> application:start(gnuart).

	ok

	

From a valid process, subscribe it to gnuart

	2> gnuart:subscribe().

	{ok,#Ref<0.0.0.39>}

	

Open the device before send some command

	3> gnuart:open().

	ok

	4> flush().

	Shell got {got,#Ref<0.0.0.39>,<<"device_open">>}

	ok

Send bytes

	5> gnuart:flush("AA0065").

	{ok,flush}

	

The response is delivered to the calling process (subscribed)

	6> flush().

	Shell got {got,#Ref<0.0.0.39>,<<"FF0000">>}

	ok

	

The device can be closed using

	7> gnuart:close().

	Shell got {got,#Ref<0.0.0.37>,<<"device_close">>}

	ok

	

However you can unsubscribe a process

	8> gnuart:unsubscribe(Ref).

	{ok,unsubscribe}
