| 79 | If you say Y here, it will be possible to use a serial port as the |

| 359 | help |
| 360 | This option replaces the "console=ttyO" argument with the matching |
| 361 | ttyS argument if the user did not specified it on the command line. |
| 362 | This ensures that the user can see the kernel output during boot |
| 363 | which he wouldn't see otherwise. The getty has still to be configured |
| 364 | for ttyS instead of ttyO regardless of this option. |
| 365 | This option is intended for people who "automatically" enable this |
| 366 | driver without knowing that this driver requires a different console= |
| 367 | argument. If you read this, please keep this option disabled and |
| 368 | instead update your kernel command line. If you prepare a kernel for a |
| 369 | distribution or other kind of larger user base then you probably want |
| 370 | to keep this option enabled. Otherwise people might complain about a |
| 371 | not booting kernel because the serial console remains silent in case |
| 372 | they forgot to update the command line. |
