13 tristate "8250/16550 and compatible serial support"
14 depends on (BROKEN || !SPARC)
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
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
33 BTW1: If you have a mouseman serial mouse which is not recognized by
34 the X window system, try running gpm first.
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.
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.
43 config SERIAL_8250_CONSOLE
44 bool "Console on 8250/16550 and compatible serial port"
45 depends on SERIAL_8250=y
46 select SERIAL_CORE_CONSOLE
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
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.)
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
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 correponding port is
70 "earlycon=uart8250,io,0x3f8,9600n8"
71 "earlycon=uart8250,mmio,0xff5e0000,115200n8".
72 it will not only setup early console.

152 driver, say Y here. This includes HUB6 support, shared serial
153 interrupts, special multiport support, support for more than the
154 four COM 1/2/3/4 boards, etc.
156 Note that the answer to this question won't directly affect the
157 kernel: saying N will just cause the configurator to skip all
158 the questions about serial driver options. If unsure, say N.

161 bool "Support more than 4 legacy serial ports"
162 depends on SERIAL_8250_EXTENDED && !IA64
164 Say Y here if you have dumb serial boards other than the four
165 standard COM 1/2/3/4 ports. This may happen if you have an AST
166 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
167 from <http://www.tldp.org/docs.html#howto>), or other custom
168 serial port hardware which acts similar to standard serial port
169 hardware. If you only use the standard COM 1/2/3/4 ports, you can
170 say N here to save some memory. You can also say Y if you have an

235 depends on SERIAL_8250_EXTENDED
237 Say Y here if you want the kernel to try to guess which IRQ
