| This enables a UART driver for the POSIX ARCH with up to 2 UARTs. |
| For the first UART port, the driver can be configured |
| to either connect to the terminal from which native_posix was run, or into |
| one dedicated pseudoterminal for that UART. |

| help |
| Connect this UART to its own pseudoterminal. This is the preferred |
| option for users who want to use Zephyr's shell. |
| Moreover this option does not conflict with any other native_posix |
| backend which may use the calling shell standard input/output. |

| help |
| Connect this UART to the stdin & stdout of the calling shell/terminal |
| which invoked the native_posix executable. This is good enough for |
| automated testing, or when feeding from a file/pipe. |
| Note that other, non UART messages, will also be printed to the |
| terminal. This option should NOT be used in conjunction with |
| NATIVE_POSIX_STDIN_CONSOLE |
| It is strongly discouraged to try to use this option with the new |
| shell interactively, as the default terminal configuration is NOT |
| appropriate for interactive use. |

| When this option is selected a new command line switch is provided: |
| ``--wait_uart`` |
| When ``--wait_uart`` is used, writes to the UART will be held until a |
| client has connected to the slave side of the pseudoterminal. |
| Otherwise writes are sent irrespectively. |

| help |
| If the native_posix executable is called with the --attach_uart |
| command line option, this will be the default command which will be |
| run to attach a new terminal to the 1st UART. |
| Note that this command must have one, and only one, '%s' as |
| placeholder for the pseudoterminal device name (e.g. /dev/pts/35) |
| This is only applicable if the UART_0 is configured to use its own |
| PTY with NATIVE_UART_0_ON_OWN_PTY. |
| The 2nd UART will not be affected by this option. |
| If you are using GNOME, then you can use this command string |
| 'gnome-terminal -- screen %s' |
