CONFIG_SERIAL_CONSOLE: Support for serial port console

General informations

The Linux kernel configuration item CONFIG_SERIAL_CONSOLE has multiple definitions:

Support for serial port console found in arch/m68k/Kconfig.devices

The configuration item CONFIG_SERIAL_CONSOLE:

• prompt: Support for serial port console
• type: bool
• depends on: CONFIG_AMIGA_BUILTIN_SERIAL = CONFIG_y
• defined in arch/m68k/Kconfig.devices
• found in Linux kernels: 3.2–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

If you say Y here, it will be possible to use a serial port as the system console (the system console is the device which receives all kernel messages and warnings and which allows logins in single user mode). This could be useful if some terminal or printer is connected to that serial port.

Even if you say Y here, the currently visible virtual console (/dev/tty0) will still be used as the system console by default, but you can alter that using a kernel command line option such as "console=ttyS1". (Try "man bootparam" or see the documentation of your boot loader about how to pass options to the kernel at boot time.)

If you don't have a graphical console and you say Y here, the kernel will automatically use the first serial line, /dev/ttyS0, as system console.

If unsure, say N.
