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

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

1127 Say Y here if you wish to use a SCC or SMC CPM UART as the system
1128 console (the system console is the device which receives all kernel
1129 messages and warnings and which allows logins in single user mode).
1130
1131 Even if you say Y here, the currently visible framebuffer console
1132 (/dev/tty0) will still be used as the system console by default, but
1133 you can alter that using a kernel command line option such as
1134 "console=ttyCPM0". (Try "man bootparam" or see the documentation of
1135 your boot loader (lilo or loadlin) about how to pass options to the
1136 kernel at boot time.)
