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.o. If you want to compile it as
77 a module, say M here and read <file:Documentation/modules.txt>.
80 config SERIAL_8250_EXTENDED
81 bool "Extended 8250/16550 serial driver options"
82 depends on SERIAL_8250
84 If you wish to use any non-standard features of the standard "dumb"
85 driver, say Y here. This includes HUB6 support, shared serial
86 interrupts, special multiport support, support for more than the
87 four COM 1/2/3/4 boards, etc.
89 Note that the answer to this question won't directly affect the
90 kernel: saying N will just cause the configurator to skip all
91 the questions about serial driver options. If unsure, say N.
93 config SERIAL_8250_MANY_PORTS
94 bool "Support more than 4 serial ports"
95 depends on SERIAL_8250_EXTENDED
97 Say Y here if you have dumb serial boards other than the four
98 standard COM 1/2/3/4 ports. This may happen if you have an AST
99 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
100 from <http://www.linuxdoc.org/docs.html#howto>), or other custom
101 serial port hardware which acts similar to standard serial port
102 hardware. If you only use the standard COM 1/2/3/4 ports, you can
103 say N here to save some memory. You can also say Y if you have an
104 "intelligent" multiport card such as Cyclades, Digiboards, etc.
106 config SERIAL_8250_SHARE_IRQ
107 bool "Support for sharing serial interrupts"
108 depends on SERIAL_8250_EXTENDED
110 Some serial boards have hardware support which allows multiple dumb
111 serial ports on the same board to share a single IRQ. To enable
112 support for this in the serial driver, say Y here.
114 config SERIAL_8250_DETECT_IRQ
115 bool "Autodetect IRQ on standard ports (unsafe)"
116 depends on SERIAL_8250_EXTENDED
118 Say Y here if you want the kernel to try to guess which IRQ
119 to use for your serial port.
121 This is considered unsafe; it is far better to configure the IRQ in
122 a boot script using the setserial command.
126 config SERIAL_8250_MULTIPORT
127 bool "Support special multiport boards"
128 depends on SERIAL_8250_EXTENDED
130 Some multiport serial ports have special ports which are used to
131 signal when there are any serial ports on the board which need
132 servicing. Say Y here to enable the serial driver to take advantage
133 of those special I/O ports.
135 config SERIAL_8250_RSA
136 bool "Support RSA serial ports"
137 depends on SERIAL_8250_EXTENDED

143 config SERIAL_8250_ACORN
144 tristate "Acorn expansion card serial port support"
145 depends on ARM && ARCH_ACORN && SERIAL_8250
147 If you have an Atomwide Serial card or Serial Port card for an Acorn
148 system, say Y to this option. The driver can handle 1, 2, or 3 port
149 cards. If unsure, say N.
152 bool "Anakin serial port support"
153 depends on ARM && ARCH_ANAKIN
155 ::: To be written :::
157 config SERIAL_ANAKIN_CONSOLE
158 bool "Console on Anakin serial port"
159 depends on SERIAL_ANAKIN
161 Even if you say Y here, the currently visible virtual console
162 (/dev/tty0) will still be used as the system console by default, but
163 you can alter that using a kernel command line option such as
164 "console=ttyAN0". (Try "man bootparam" or see the documentation of
165 your boot loader (lilo or loadlin) about how to pass options to the
166 kernel at boot time.)

180 Integrator platform, say Y or M here.
184 config SERIAL_AMBA_CONSOLE
185 bool "Support for console on AMBA serial port"
186 depends on SERIAL_AMBA=y
188 Say Y here if you wish to use an AMBA PrimeCell UART as the system
189 console (the system console is the device which receives all kernel
190 messages and warnings and which allows logins in single user mode).
192 Even if you say Y here, the currently visible framebuffer console
193 (/dev/tty0) will still be used as the system console by default, but
194 you can alter that using a kernel command line option such as
195 "console=ttyAM0". (Try "man bootparam" or see the documentation of
196 your boot loader (lilo or loadlin) about how to pass options to the
197 kernel at boot time.)

210 config SERIAL_CLPS711X_CONSOLE
211 bool "Support for console on CLPS711X serial port"
212 depends on SERIAL_CLPS711X=y
214 Even if you say Y here, the currently visible virtual console
215 (/dev/tty0) will still be used as the system console by default, but
216 you can alter that using a kernel command line option such as
217 "console=ttyCL1". (Try "man bootparam" or see the documentation of

223 depends on SERIAL_CLPS711X=y
225 ::: To be written :::
228 bool "DECstation serial support"
229 depends on DECSTATION
231 This selects whether you want to be asked about drivers for
232 DECstation serial ports.
234 Note that the answer to this question won't directly affect the
235 kernel: saying N will just cause the configurator to skip all
236 the questions about DECstation serial ports.
240 config SERIAL_DEC_CONSOLE
241 bool "Support for console on a DECstation serial port"
242 depends on SERIAL_DEC
244 If you say Y here, it will be possible to use a serial port as the
245 system console (the system console is the device which receives all
246 kernel messages and warnings and which allows logins in single user
247 mode). Note that the firmware uses ttyS0 as the serial console on
248 the Maxine and ttyS2 on the others.
253 bool "DZ11 Serial Support"
254 depends on SERIAL_DEC && MIPS32
256 DZ11-family serial controllers for VAXstations, including the
257 DC7085, M7814, and M7819.

268 depends on ARM && FOOTBRIDGE
270 If you have a machine based on a 21285 (Footbridge) StrongARM(R)/
271 PCI bridge you can enable its onboard serial port by enabling this
274 config SERIAL_21285_OLD
275 bool "Use /dev/ttyS0 device (OBSOLETE)"
276 depends on SERIAL_21285=y && OBSOLETE
278 Use the old /dev/ttyS name, major 4 minor 64. This is obsolete
279 and will be removed during later 2.5 development.
281 config SERIAL_21285_CONSOLE
282 bool "Console on DC21285 serial port"
283 depends on SERIAL_21285=y
285 If you have enabled the serial port on the 21285 footbridge you can
286 make it the console by answering Y to this option.
288 Even if you say Y here, the currently visible virtual console
289 (/dev/tty0) will still be used as the system console by default, but
290 you can alter that using a kernel command line option such as
291 "console=ttyFB". (Try "man bootparam" or see the documentation of
292 your boot loader (lilo or loadlin) about how to pass options to the
293 kernel at boot time.)
296 bool "Excalibur serial port (uart00) support"
297 depends on ARM && ARCH_CAMELOT
299 Say Y here if you want to use the hard logic uart on Excalibur. This
300 driver also supports soft logic implentations of this uart core.
302 config SERIAL_UART00_CONSOLE
303 bool "Support for console on Excalibur serial port"
304 depends on SERIAL_UART00
306 Say Y here if you want to support a serial console on an Excalibur
307 hard logic uart or uart00 IP core.
309 Even if you say Y here, the currently visible virtual console
310 (/dev/tty0) will still be used as the system console by default, but
311 you can alter that using a kernel command line option such as
312 "console=ttyS1". (Try "man bootparam" or see the documentation of
313 your boot loader (lilo or loadlin) about how to pass options to the
314 kernel at boot time.)
317 bool "SA1100 serial port support"
318 depends on ARM && ARCH_SA1100
320 If you have a machine based on a SA1100/SA1110 StrongARM(R) CPU you
321 can enable its onboard serial port by enabling this option.
322 Please read <file:Documentation/arm/SA1100/serial_UART> for further
325 config SERIAL_SA1100_CONSOLE
326 bool "Console on SA1100 serial port"
327 depends on SERIAL_SA1100
329 If you have enabled the serial port on the SA1100/SA1110 StrongARM
330 CPU you can make it the console by answering Y to this option.
332 Even if you say Y here, the currently visible virtual console
333 (/dev/tty0) will still be used as the system console by default, but
334 you can alter that using a kernel command line option such as
335 "console=ttySA0". (Try "man bootparam" or see the documentation of

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