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}
