The standard answer is Y. People who might say N 16 here are those that are setting up dedicated Ethernet WWW/FTP 17 servers, or users that have one of the various bus mice instead of a 18 serial mouse and don't intend to use their machine's standard serial 19 port for anything. (Note that the Cyclades and Stallion multi 20 serial port drivers do not need this driver built in for them to 21 work.) 22 23 To compile this driver as a module, choose M here: the 24 module will be called 8250. 25 [WARNING: Do not compile this driver as a module if you are using 26 non-standard serial ports, since the configuration information will 27 be lost when the driver is unloaded. This limitation may be lifted 28 in the future.] 29 30 BTW1: If you have a mouseman serial mouse which is not recognized by 31 the X window system, try running gpm first. 32 33 BTW2: If you intend to use a software modem (also called Winmodem) 34 under Linux, forget it. These modems are crippled and require 35 proprietary drivers which are only available under Windows. 36 37 Most people will say Y or M here, so that they can use serial mice, 38 modems and similar devices connecting to the standard serial ports. 39 40config SERIAL_8250_CONSOLE 41 bool "Console on 8250/16550 and compatible serial port" 42 depends on SERIAL_8250=y 43 select SERIAL_CORE_CONSOLE 44 ---help--- 45 If you say Y here, it will be possible to use a serial port as the 46 system console (the system console is the device which receives all 47 kernel messages and warnings and which allows logins in single user 48 mode). This could be useful if some terminal or printer is connected 49 to that serial port. 50 51 Even if you say Y here, the currently visible virtual console 52 (/dev/tty0) will still be used as the system console by default, but 53 you can alter that using a kernel command line option such as 54 "console=ttyS1". (Try "man bootparam" or see the documentation of 55 your boot loader (grub or lilo or loadlin) about how to pass options 56 to the kernel at boot time.) 57 58 If you don't have a VGA card installed and you say Y here, the 59 kernel will automatically use the first serial line, /dev/ttyS0, as 60 system console. 61 62 You can set that using a kernel command line option such as 63 "console=uart8250,io,0x3f8,9600n8" 64 "console=uart8250,mmio,0xff5e0000,115200n8". 65 and it will switch to normal serial console when the corresponding 66 port is ready. 67 "earlycon=uart8250,io,0x3f8,9600n8" 68 "earlycon=uart8250,mmio,0xff5e0000,115200n8". 69 it will not only setup early console. 70 71 If unsure, say N. 72 73config FIX_EARLYCON_MEM 74 bool 75 depends on X86 76 default y 77 78config SERIAL_8250_GSC 79 tristate 80 depends on SERIAL_8250 && GSC 81 default SERIAL_8250 82 83config SERIAL_8250_PCI 84 tristate "8250/16550 PCI device support" if EXPERT 85 depends on SERIAL_8250 && PCI 86 default SERIAL_8250 87 help 88 This builds standard PCI serial support.
