13 | ---help--- | ||
14 | This selects whether you want to include the driver for the standard | ||
15 | serial ports. 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. | ||

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. | ||
