12 tristate "8250/16550 and compatible serial support (EXPERIMENTAL)"
13 depends on EXPERIMENTAL
15 This selects whether you want to include the driver for the standard
16 serial ports. The standard answer is Y. People who might say N
17 here are those that are setting up dedicated Ethernet WWW/FTP
18 servers, or users that have one of the various bus mice instead of a
19 serial mouse and don't intend to use their machine's standard serial
20 port for anything. (Note that the Cyclades and Stallion multi
21 serial port drivers do not need this driver built in for them to
24 If you want to compile this driver as a module, say M here and read
25 <file:Documentation/modules.txt>. The module will be called
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 (EXPERIMENTAL)"
44 depends on SERIAL_8250=y
46 If you say Y here, it will be possible to use a serial port as the
47 system console (the system console is the device which receives all
48 kernel messages and warnings and which allows logins in single user
49 mode). This could be useful if some terminal or printer is connected
52 Even if you say Y here, the currently visible virtual console
53 (/dev/tty0) will still be used as the system console by default, but
54 you can alter that using a kernel command line option such as
55 "console=ttyS1". (Try "man bootparam" or see the documentation of
56 your boot loader (lilo or loadlin) about how to pass options to the
59 If you don't have a VGA card installed and you say Y here, the
60 kernel will automatically use the first serial line, /dev/ttyS0, as
66 tristate "8250/16550 PCMCIA device support"
67 depends on PCMCIA && SERIAL_8250
69 Say Y here to enable support for 16-bit PCMCIA serial devices,
70 including serial port cards, modems, and the modem functions of
71 multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
72 credit-card size devices often used with laptops.)
74 This driver is also available as a module ( = code which can be
75 inserted in and removed from the running kernel whenever you want).
76 The module will be called serial_cs. If you want to compile it as
77 a module, say M here and read <file:Documentation/modules.txt>.
80 config SERIAL_8250_ACPI
81 bool "8250/16550 device discovery via ACPI namespace"
85 If you wish to enable serial port discovery via the ACPI
86 namespace, say Y here. If unsure, say N.
88 config SERIAL_8250_HCDP
89 bool "8250/16550 device discovery support via EFI HCDP table"
92 If you wish to make the serial console port described by the EFI
93 HCDP table available for use as serial console or general
94 purpose port, say Y here. See
95 <http://www.dig64.org/specifications/DIG64_HCDPv10a_01.pdf>.
97 config SERIAL_8250_EXTENDED
98 bool "Extended 8250/16550 serial driver options"
99 depends on SERIAL_8250
101 If you wish to use any non-standard features of the standard "dumb"
102 driver, say Y here. This includes HUB6 support, shared serial
103 interrupts, special multiport support, support for more than the
104 four COM 1/2/3/4 boards, etc.
106 Note that the answer to this question won't directly affect the
107 kernel: saying N will just cause the configurator to skip all
108 the questions about serial driver options. If unsure, say N.
110 config SERIAL_8250_MANY_PORTS
111 bool "Support more than 4 serial ports"
112 depends on SERIAL_8250_EXTENDED
114 Say Y here if you have dumb serial boards other than the four
115 standard COM 1/2/3/4 ports. This may happen if you have an AST
116 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
117 from <http://www.tldp.org/docs.html#howto>), or other custom
118 serial port hardware which acts similar to standard serial port
119 hardware. If you only use the standard COM 1/2/3/4 ports, you can
120 say N here to save some memory. You can also say Y if you have an
121 "intelligent" multiport card such as Cyclades, Digiboards, etc.
123 config SERIAL_8250_SHARE_IRQ
124 bool "Support for sharing serial interrupts"
125 depends on SERIAL_8250_EXTENDED
127 Some serial boards have hardware support which allows multiple dumb
128 serial ports on the same board to share a single IRQ. To enable
129 support for this in the serial driver, say Y here.
131 config SERIAL_8250_DETECT_IRQ
132 bool "Autodetect IRQ on standard ports (unsafe)"
133 depends on SERIAL_8250_EXTENDED
135 Say Y here if you want the kernel to try to guess which IRQ
136 to use for your serial port.
138 This is considered unsafe; it is far better to configure the IRQ in
139 a boot script using the setserial command.
143 config SERIAL_8250_MULTIPORT
144 bool "Support special multiport boards"
145 depends on SERIAL_8250_EXTENDED
147 Some multiport serial ports have special ports which are used to
148 signal when there are any serial ports on the board which need
149 servicing. Say Y here to enable the serial driver to take advantage
150 of those special I/O ports.
152 config SERIAL_8250_RSA
153 bool "Support RSA serial ports"
154 depends on SERIAL_8250_EXTENDED

162 depends on ARM && ARCH_ACORN && SERIAL_8250
164 If you have an Atomwide Serial card or Serial Port card for an Acorn
165 system, say Y to this option. The driver can handle 1, 2, or 3 port
166 cards. If unsure, say N.

178 Even if you say Y here, the currently visible virtual console
179 (/dev/tty0) will still be used as the system console by default, but
180 you can alter that using a kernel command line option such as
181 "console=ttyAN0". (Try "man bootparam" or see the documentation of
182 your boot loader (lilo or loadlin) about how to pass options to the
183 kernel at boot time.)

201 config SERIAL_AMBA_CONSOLE
202 bool "Support for console on AMBA serial port"
203 depends on SERIAL_AMBA=y
205 Say Y here if you wish to use an AMBA PrimeCell UART as the system
206 console (the system console is the device which receives all kernel
207 messages and warnings and which allows logins in single user mode).
209 Even if you say Y here, the currently visible framebuffer console
210 (/dev/tty0) will still be used as the system console by default, but
211 you can alter that using a kernel command line option such as
212 "console=ttyAM0". (Try "man bootparam" or see the documentation of

251 config SERIAL_DZ_CONSOLE
252 bool "Support console on DECstation DZ serial driver"
253 depends on SERIAL_DZ=y
255 If you say Y here, it will be possible to use a serial port as the
256 system console (the system console is the device which receives all
257 kernel messages and warnings and which allows logins in single user
258 mode). Note that the firmware uses ttyS0 as the serial console on
259 the Maxine and ttyS2 on the others.
264 tristate "DC21285 serial port support"
265 depends on ARM && FOOTBRIDGE
267 If you have a machine based on a 21285 (Footbridge) StrongARM(R)/
268 PCI bridge you can enable its onboard serial port by enabling this
271 config SERIAL_21285_OLD
272 bool "Use /dev/ttyS0 device (OBSOLETE)"
273 depends on SERIAL_21285=y && OBSOLETE
275 Use the old /dev/ttyS name, major 4 minor 64. This is obsolete
276 and will be removed during later 2.5 development.
278 config SERIAL_21285_CONSOLE
279 bool "Console on DC21285 serial port"
280 depends on SERIAL_21285=y
282 If you have enabled the serial port on the 21285 footbridge you can
283 make it the console by answering Y to this option.
285 Even if you say Y here, the currently visible virtual console
286 (/dev/tty0) will still be used as the system console by default, but
287 you can alter that using a kernel command line option such as
288 "console=ttyFB". (Try "man bootparam" or see the documentation of
289 your boot loader (lilo or loadlin) about how to pass options to the
290 kernel at boot time.)
293 bool "Excalibur serial port (uart00) support"
294 depends on ARM && ARCH_CAMELOT
296 Say Y here if you want to use the hard logic uart on Excalibur. This
297 driver also supports soft logic implentations of this uart core.
299 config SERIAL_UART00_CONSOLE
300 bool "Support for console on Excalibur serial port"
301 depends on SERIAL_UART00
303 Say Y here if you want to support a serial console on an Excalibur
304 hard logic uart or uart00 IP core.
306 Even if you say Y here, the currently visible virtual console
307 (/dev/tty0) will still be used as the system console by default, but
308 you can alter that using a kernel command line option such as
309 "console=ttyS1". (Try "man bootparam" or see the documentation of

311 kernel at boot time.)
314 bool "SA1100 serial port support"
315 depends on ARM && ARCH_SA1100
317 If you have a machine based on a SA1100/SA1110 StrongARM(R) CPU you
318 can enable its onboard serial port by enabling this option.
319 Please read <file:Documentation/arm/SA1100/serial_UART> for further
322 config SERIAL_SA1100_CONSOLE
323 bool "Console on SA1100 serial port"
324 depends on SERIAL_SA1100
326 If you have enabled the serial port on the SA1100/SA1110 StrongARM
327 CPU you can make it the console by answering Y to this option.
329 Even if you say Y here, the currently visible virtual console
330 (/dev/tty0) will still be used as the system console by default, but
331 you can alter that using a kernel command line option such as
332 "console=ttySA0". (Try "man bootparam" or see the documentation of

342 tristate "Sun Zilog8530 serial support"
343 depends on SPARC32 || SPARC64
345 This driver supports the Zilog8530 serial ports found on many Sparc
346 systems. Say Y or M if you want to be able to these serial ports.
349 tristate "Sun SU serial support"
350 depends on (SPARC32 || SPARC64) && PCI
352 This driver supports the 8250 serial ports that run the keyboard and
353 mouse on (PCI) UltraSPARC systems. Say Y or M if you want to be able
354 to these serial ports.
357 tristate "Serial MUX support"
361 Saying Y here will enable the hardware MUX serial driver for
362 the Nova and K class systems. The hardware MUX is not 8250/16550
363 compatible therefore the /dev/ttyB0 device is shared between the
364 Serial MUX and the PDC software console. The following steps
365 need to be completed to use the Serial MUX:
367 1. create the device entry (mknod /dev/ttyB0 c 11 0)
368 2. Edit the /etc/inittab to start a getty listening on /dev/ttyB0
369 3. Add device ttyB0 to /etc/securetty (if you want to log on as
370 root on this console.)
371 4. Change the kernel command console parameter to: console=ttyB0
373 config SERIAL_MUX_CONSOLE
374 bool "Support for console on serial MUX"
375 depends on SERIAL_MUX
379 bool "PDC software console support"
380 depends on PARISC && !SERIAL_MUX
383 Saying Y here will enable the software based PDC console to be
384 used as the system console. This is useful for machines in
385 which the hardware based console has not been written yet. The
386 following steps must be competed to use the PDC console:
388 1. create the device entry (mknod /dev/ttyB0 c 11 0)
389 2. Edit the /etc/inittab to start a getty listening on /dev/ttyB0
