- * uart.c
- *
- *  Created on: Aug 5, 2019
- *      Author: Cristian Fatu
- *      Implements basic UART functionality, over Uart Lite linux driver, using termios.
- *      After booting linux, a device like "/dev/ttyUL1" must be present.
- *      These functions work in both canonic and not canonic modes.
- *      In the canonic communication mode, the received chars can be retrieved by read only after \n is detected.
- *      In the non canonic communication mode, the received chars can be retrieved by read as they are received.

-Parameters:

-          unsigned char canonic		- communication mode
-                          1 	- canonic communication (chars are only received after \n is detected).

-Description:
-        Initializes the UART device.
-        When calling the function, the device name (usually "/dev/ttyUL1") must be filled in dev->name and the baud rate must be filled in dev->rate.
-        The canonic function parameter indicates communication mode (canonic or not).
-        In the canonic communication mode, the received chars can be retrieved by read only after \n is detected.
-        In the non canonic communication mode, the received chars can be retrieved by read as they are received, as the non canonic mode is configured with no
-wait.
