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.

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.

186 This special driver allows you to temporary use NMI debugger port

188
189 Unlike KDB's disable_nmi command, with this driver you are always
190 able to go back to the debugger using KGDB escape sequence ($3#33).
191 This is because this console driver processes the input in NMI
192 context, and thus is able to intercept the magic sequence.
193
194 Note that since the console interprets input and uses polling
195 communication methods, for things like PPP you still must fully
196 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
197 use raw console.

750 access the built-in serial ports on powermacs will need to
