Raspberry Pi Pico Pinout
------------------------
| Raspberry Pi Pico GPIO | Function |
|:----------------------:|:--------:|
| GPIO16 (Pin 21) | UART0 TX |
| GPIO17 (Pin 22) | UART0 RX |
| GPIO4 (Pin 6) | UART1 TX |
| GPIO5 (Pin 7) | UART1 RX |
UART0:
| Raspberry Pi Pico GPIO | Function |
|:----------------------:|:---------:|
| GPIO0 (Pin 1) | TX |
| GPIO1 (Pin 2) | RX |
| GPIO2 (Pin 4) | CTS |
| GPIO3 (Pin 5) | RTS |
| GPIO4 (Pin 6) | DTR |
| GPIO5 (Pin 7) | DSR |
UART1:
| Raspberry Pi Pico GPIO | Function |
|:----------------------:|:---------:|
| GPIO8 (Pin 11) | TX |
| GPIO9 (Pin 12) | RX |
| GPIO10 (Pin 14) | CTS |

Optional Hardware Flow and Line control
------------------------------
Hardware Flow-control (RTS/CTS) is disabled by default, but can be compiled in by running:
``` bash
cmake -DFLOW_CONTROL .
make
```
Line control (DTR/DSR) is disabled by default, but can be compiled in by running:
``` bash
cmake -DLINE_CONTROL .
make
```
To enable both:
``` bash
cmake -DLINE_CONTROL -DFLOW_CONTROL .
make
```
