17 This selects whether you want to include the driver for the standard
18 serial ports. The standard answer is Y. People who might say N
19 here are those that are setting up dedicated Ethernet WWW/FTP
20 servers, or users that have one of the various bus mice instead of a
21 serial mouse and don't intend to use their machine's standard serial
22 port for anything. (Note that the Cyclades and Stallion multi
23 serial port drivers do not need this driver built in for them to
24 work.)
25
26 To compile this driver as a module, choose M here: the
27 module will be called 8250.
28 [WARNING: Do not compile this driver as a module if you are using
29 non-standard serial ports, since the configuration information will
30 be lost when the driver is unloaded. This limitation may be lifted
31 in the future.]
32
33 BTW1: If you have a mouseman serial mouse which is not recognized by
34 the X window system, try running gpm first.
35
36 BTW2: If you intend to use a software modem (also called Winmodem)
37 under Linux, forget it. These modems are crippled and require
38 proprietary drivers which are only available under Windows.
39
40 Most people will say Y or M here, so that they can use serial mice,
41 modems and similar devices connecting to the standard serial ports.

47 ---help---
48 If you say Y here, it will be possible to use a serial port as the
49 system console (the system console is the device which receives all
50 kernel messages and warnings and which allows logins in single user
51 mode). This could be useful if some terminal or printer is connected
52 to that serial port.
53
54 Even if you say Y here, the currently visible virtual console
55 (/dev/tty0) will still be used as the system console by default, but
56 you can alter that using a kernel command line option such as
57 "console=ttyS1". (Try "man bootparam" or see the documentation of
58 your boot loader (grub or lilo or loadlin) about how to pass options
59 to the kernel at boot time.)
60
61 If you don't have a VGA card installed and you say Y here, the
62 kernel will automatically use the first serial line, /dev/ttyS0, as
63 system console.
64
65 You can set that using a kernel command line option such as
66 "console=uart8250,io,0x3f8,9600n8"
67 "console=uart8250,mmio,0xff5e0000,115200n8".
68 and it will switch to normal serial console when the corresponding
69 port is ready.
70 "earlycon=uart8250,io,0x3f8,9600n8"
71 "earlycon=uart8250,mmio,0xff5e0000,115200n8".
72 it will not only setup early console.

1113 Even if you say Y here, the currently visible framebuffer console
1114 (/dev/tty0) will still be used as the system console by default, but
1115 you can alter that using a kernel command line option such as
1116 "console=ttyCPM0". (Try "man bootparam" or see the documentation of
1117 your boot loader (lilo or loadlin) about how to pass options to the
1118 kernel at boot time.)
