3# you somehow have an implicit or explicit dependency on SERIAL_8250.

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

12 select SERIAL_CORE
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.

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.
