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

114 depends on SERIAL_8250
117 Set this to the number of serial ports you want the driver
118 to support. This includes any ports discovered via ACPI or
119 PCI enumeration and any ports that may be added at run-time
120 via hot-plug, or any ISA multi-port serial cards.

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

147 bool "Support more than 4 legacy serial ports"
148 depends on SERIAL_8250_EXTENDED && !IA64

151 standard COM 1/2/3/4 ports. This may happen if you have an AST
152 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
153 from <http://www.tldp.org/docs.html#howto>), or other custom
154 serial port hardware which acts similar to standard serial port
155 hardware. If you only use the standard COM 1/2/3/4 ports, you can
156 say N here to save some memory. You can also say Y if you have an

221 depends on SERIAL_8250_EXTENDED
223 Say Y here if you want the kernel to try to guess which IRQ
224 to use for your serial port.

350 appear as /dev/ttyATn (major 204, minor starting at 154)

352 64). This is necessary if you also want other UARTs, such as
353 external 8250/16C550 compatible UARTs.
354 The ttySn nodes are legally reserved for the 8250 serial driver
355 but are often misused by other serial drivers.
357 To use this, you should create suitable ttyATn device nodes in
358 /dev/, and pass "console=ttyATn" to the kernel.
