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

77 disable this feature if you only need legacy serial support.
80 config SERIAL_8250_PNP
81 tristate "8250/16550 PNP device support" if EMBEDDED
82 depends on SERIAL_8250 && PNP
85 This builds standard PNP serial support. You may be able to
86 disable this feature if you only need legacy serial support.

90 depends on SERIAL_8250 && HP300
94 tristate "8250/16550 PCMCIA device support"
95 depends on PCMCIA && SERIAL_8250
97 Say Y here to enable support for 16-bit PCMCIA serial devices,
98 including serial port cards, modems, and the modem functions of
99 multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
100 credit-card size devices often used with laptops.)

114 PCI enumeration and any ports that may be added at run-time

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

143 depends on SERIAL_8250_EXTENDED && !IA64
145 Say Y here if you have dumb serial boards other than the four
146 standard COM 1/2/3/4 ports. This may happen if you have an AST
147 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
148 from <http://www.tldp.org/docs.html#howto>), or other custom
149 serial port hardware which acts similar to standard serial port
150 hardware. If you only use the standard COM 1/2/3/4 ports, you can
151 say N here to save some memory. You can also say Y if you have an
152 "intelligent" multiport card such as Cyclades, Digiboards, etc.
154 config SERIAL_8250_SHARE_IRQ
155 bool "Support for sharing serial interrupts"
156 depends on SERIAL_8250_EXTENDED
158 Some serial boards have hardware support which allows multiple dumb
159 serial ports on the same board to share a single IRQ. To enable
160 support for this in the serial driver, say Y here.
162 config SERIAL_8250_DETECT_IRQ
163 bool "Autodetect IRQ on standard ports (unsafe)"
164 depends on SERIAL_8250_EXTENDED
166 Say Y here if you want the kernel to try to guess which IRQ
167 to use for your serial port.
169 This is considered unsafe; it is far better to configure the IRQ in
170 a boot script using the setserial command.

325 appear as /dev/ttyATn (major 204, minor starting at 154)
326 instead of the normal /dev/ttySn (major 4, minor starting at
327 64). This is necessary if you also want other UARTs, such as
328 external 8250/16C550 compatible UARTs.
329 The ttySn nodes are legally reserved for the 8250 serial driver
330 but are often misused by other serial drivers.
332 To use this, you should create suitable ttyATn device nodes in
333 /dev/, and pass "console=ttyATn" to the kernel.
