The standard answer is Y. People who might say N here are those that are setting up dedicated Ethernet WWW/FTP servers, or users that have one of the various bus mice instead of a serial mouse and don't intend to use their machine's standard serial port for anything. (Note that the Cyclades and Stallion multi serial port drivers do not need this driver built in for them to work.) To compile this driver as a module, choose M here: the module will be called 8250. [WARNING: Do not compile this driver as a module if you are using non-standard serial ports, since the configuration information will be lost when the driver is unloaded. This limitation may be lifted in the future.] BTW1: If you have a mouseman serial mouse which is not recognized by the X window system, try running gpm first. BTW2: If you intend to use a software modem (also called Winmodem) under Linux, forget it. These modems are crippled and require proprietary drivers which are only available under Windows. Most people will say Y or M here, so that they can use serial mice, modems and similar devices connecting to the standard serial ports. config SERIAL_8250_CONSOLE bool "Console on 8250/16550 and compatible serial port" depends on SERIAL_8250=y select SERIAL_CORE_CONSOLE ---help--- 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 (grub or lilo or loadlin) about how to pass options to the kernel at boot time.) If you don't have a VGA card installed and you say Y here, the kernel will automatically use the first serial line, /dev/ttyS0, as system console.

This includes HUB6 support, shared serial interrupts, special multiport support, support for more than the four COM 1/2/3/4 boards, etc. Note that the answer to this question won't directly affect the kernel: saying N will just cause the configurator to skip all the questions about serial driver options. If unsure, say N. config SERIAL_8250_MANY_PORTS bool "Support more than 4 legacy serial ports" depends on SERIAL_8250_EXTENDED && !IA64 help Say Y here if you have dumb serial boards other than the four standard COM 1/2/3/4 ports. This may happen if you have an AST FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available from <http://www.tldp.org/docs.html#howto>), or other custom serial port hardware which acts similar to standard serial port hardware. If you only use the standard COM 1/2/3/4 ports, you can say N here to save some memory.

This is necessary if you also want other UARTs, such as external 8250/16C550 compatible UARTs. The ttySn nodes are legally reserved for the 8250 serial driver but are often misused by other serial drivers. To use this, you should create suitable ttyATn device nodes in /dev/, and pass "console=ttyATn" to the kernel. Say Y if you have an external 8250/16C550 UART.

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=ttyFB".

To use this, you should create suitable ttyATn device nodes in /dev/, and pass "console=ttyATn" to the kernel. Say Y if you have an external 8250/16C550 UART. If unsure, say N. config SERIAL_CLPS711X tristate "CLPS711X serial port support" depends on ARM && ARCH_CLPS711X select SERIAL_CORE help ::: To be written ::: config SERIAL_CLPS711X_CONSOLE bool "Support for console on CLPS711X serial port" depends on SERIAL_CLPS711X=y select SERIAL_CORE_CONSOLE help 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=ttyCL1". (Try "man bootparam" or see the documentation of your boot loader (lilo or loadlin) about how to pass options to the kernel at boot time.) config SERIAL_S3C2410 tristate "Samsung S3C2410/S3C2440/S3C2442/S3C2412 Serial port support" depends on ARM && ARCH_S3C2410 select SERIAL_CORE help Support for the on-chip UARTs on the Samsung S3C24XX series CPUs, providing /dev/ttySAC0, 1 and 2 (note, some machines may not provide all of these ports, depending on how the serial port pins are configured. Currently this driver supports the UARTS on the S3C2410, S3C2440, S3C2442, S3C2412 and S3C2413 CPUs. config SERIAL_S3C2410_CONSOLE bool "Support for console on S3C2410 serial port" depends on SERIAL_S3C2410=y select SERIAL_CORE_CONSOLE help Allow selection of the S3C24XX on-board serial ports for use as an virtual console.

Note that the firmware uses ttyS0 as the serial console on the Maxine and ttyS2 on the others.

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=ttyFB".
