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 serial. [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. If unsure, say N. config SERIAL_8250_HCDP bool "Console device discovery via EFI HCDP table" depends on IA64 depends on SERIAL_8250_CONSOLE=y ---help--- If you wish to make the serial console port described by the EFI HCDP table available for use as serial console, say Y here. See <http://www.dig64.org/specifications/DIG64_HCDPv10a_01.pdf>. config SERIAL_8250_CS tristate "8250/16550 PCMCIA device support" depends on PCMCIA && SERIAL_8250 ---help--- Say Y here to enable support for 16-bit PCMCIA serial devices, including serial port cards, modems, and the modem functions of multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are credit-card size devices often used with laptops.) To compile this driver as a module, choose M here: the module will be called serial_cs. If unsure, say N. config SERIAL_8250_ACPI bool "8250/16550 device discovery via ACPI namespace" default y if IA64 depends on ACPI_BUS && SERIAL_8250 ---help--- If you wish to enable serial port discovery via the ACPI namespace, say Y here. If unsure, say N. config SERIAL_8250_NR_UARTS int "Maximum number of non-legacy 8250/16550 serial ports" depends on SERIAL_8250 default "4" ---help--- Set this to the number of non-legacy serial ports you want the driver to support. This includes any ports discovered via ACPI or PCI enumeration and any ports that may be added at run-time via hot-plug. config SERIAL_8250_EXTENDED bool "Extended 8250/16550 serial driver options" depends on SERIAL_8250 help If you wish to use any non-standard features of the standard "dumb" driver, say Y here. 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. You can also say Y if you have an "intelligent" multiport card such as Cyclades, Digiboards, etc. config SERIAL_8250_SHARE_IRQ bool "Support for sharing serial interrupts" depends on SERIAL_8250_EXTENDED help Some serial boards have hardware support which allows multiple dumb serial ports on the same board to share a single IRQ. To enable support for this in the serial driver, say Y here. config SERIAL_8250_DETECT_IRQ bool "Autodetect IRQ on standard ports (unsafe)" depends on SERIAL_8250_EXTENDED help Say Y here if you want the kernel to try to guess which IRQ to use for your serial port. This is considered unsafe; it is far better to configure the IRQ in a boot script using the setserial command. If unsure, say N. config SERIAL_8250_MULTIPORT bool "Support special multiport boards" depends on SERIAL_8250_EXTENDED help Some multiport serial ports have special ports which are used to signal when there are any serial ports on the board which need servicing. Say Y here to enable the serial driver to take advantage of those special I/O ports. config SERIAL_8250_RSA bool "Support RSA serial ports" depends on SERIAL_8250_EXTENDED help ::: To be written ::: comment "Non-8250 serial port support" config SERIAL_8250_ACORN tristate "Acorn expansion card serial port support" depends on ARM && ARCH_ACORN && SERIAL_8250 help If you have an Atomwide Serial card or Serial Port card for an Acorn system, say Y to this option. The driver can handle 1, 2, or 3 port cards. If unsure, say N. config SERIAL_AMBA tristate "ARM AMBA serial port support" depends on ARM_AMBA select SERIAL_CORE help This selects the ARM(R) AMBA(R) PrimeCell UART. If you have an Integrator platform, say Y or M here. If unsure, say N. config SERIAL_AMBA_CONSOLE bool "Support for console on AMBA serial port" depends on SERIAL_AMBA=y select SERIAL_CORE_CONSOLE ---help--- Say Y here if you wish to use an AMBA PrimeCell UART 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). Even if you say Y here, the currently visible framebuffer 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=ttyAM0". (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_INTEGRATOR bool depends on SERIAL_AMBA && ARCH_INTEGRATOR default y 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 Serial port support" depends on ARM && ARCH_S3C2410 select SERIAL_CORE help Support for the on-chip UARTs on the Samsung S3C2410X CPU, 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. config SERIAL_S3C2410_CONSOLE bool "Support for console on S3C2410 serial port" depends on SERIAL_S3C2410=y help Allow selection of the S3C2410 on-board serial ports for use as an virtual console. 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=ttySACx". (Try "man bootparam" or see the documentation of your boot loader about how to pass options to the kernel at boot time.) config SERIAL_BAST_SIO bool "Support for BAST SuperIO serial ports" depends on ARCH_BAST && SERIAL_8250=y help Support for registerin the SuperIO chip on BAST board with the 8250/16550 uart code. config SERIAL_DZ bool "DECstation DZ serial driver" depends on DECSTATION select SERIAL_CORE help DZ11-family serial controllers for VAXstations, including the DC7085, M7814, and M7819. config SERIAL_DZ_CONSOLE bool "Support console on DECstation DZ serial driver" depends on SERIAL_DZ=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). Note that the firmware uses ttyS0 as the serial console on the Maxine and ttyS2 on the others. If unsure, say Y. config SERIAL_21285 tristate "DC21285 serial port support" depends on ARM && FOOTBRIDGE select SERIAL_CORE help If you have a machine based on a 21285 (Footbridge) StrongARM(R)/ PCI bridge you can enable its onboard serial port by enabling this option. config SERIAL_21285_CONSOLE bool "Console on DC21285 serial port" depends on SERIAL_21285=y select SERIAL_CORE_CONSOLE help If you have enabled the serial port on the 21285 footbridge you can make it the console by answering Y to this option. 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". (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_UART00 bool "Excalibur serial port (uart00) support" depends on ARM && ARCH_CAMELOT select SERIAL_CORE help Say Y here if you want to use the hard logic uart on Excalibur. This driver also supports soft logic implentations of this uart core. config SERIAL_UART00_CONSOLE bool "Support for console on Excalibur serial port" depends on SERIAL_UART00 select SERIAL_CORE_CONSOLE help Say Y here if you want to support a serial console on an Excalibur hard logic uart or uart00 IP core. 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 (lilo or loadlin) about how to pass options to the kernel at boot time.) config SERIAL_PXA bool "PXA serial port support" depends on ARM && ARCH_PXA select SERIAL_CORE help If you have a machine based on an Intel XScale PXA2xx CPU you can enable its onboard serial ports by enabling this option. config SERIAL_PXA_CONSOLE bool "Console on PXA serial port" depends on SERIAL_PXA select SERIAL_CORE_CONSOLE help If you have enabled the serial port on the Intel XScale PXA CPU you can make it the console by answering Y to this option. 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=ttySA0". (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_SA1100 bool "SA1100 serial port support" depends on ARM && ARCH_SA1100 select SERIAL_CORE help If you have a machine based on a SA1100/SA1110 StrongARM(R) CPU you can enable its onboard serial port by enabling this option. Please read <file:Documentation/arm/SA1100/serial_UART> for further info. config SERIAL_SA1100_CONSOLE bool "Console on SA1100 serial port" depends on SERIAL_SA1100 select SERIAL_CORE_CONSOLE help If you have enabled the serial port on the SA1100/SA1110 StrongARM CPU you can make it the console by answering Y to this option. 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=ttySA0". (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_SUNCORE bool depends on SPARC32 || SPARC64 select SERIAL_CORE select SERIAL_CORE_CONSOLE default y config SERIAL_SUNZILOG tristate "Sun Zilog8530 serial support" depends on SPARC32 || SPARC64 help This driver supports the Zilog8530 serial ports found on many Sparc systems.
