| 3 | This contains functionality for talking to UART/Serial devices on different platforms. The official client will build either `uart_posix.c` and `uart_win32.c`. Build targets for these files are contained in `client/Makefile`. |
| 4 | |
| 5 | If you want to implement support for other platforms, you need to implement the methods provided in `uart.h`. |

| 7 | ## Implementing a new driver |
| 8 | |
| 9 | Each driver is called with a string, typically containing a path or other reference to a serial port on the host. The methods outlined in `uart.h` need to be implemented. |
| 10 | |
| 11 | The hardware uses `common/usb_cdc.c` to implement a USB CDC endpoint exposed by the Atmel MCU. |
