11 tristate "8250/16550 and compatible serial support"
14 This selects whether you want to include the driver for the standard
15 serial ports. The standard answer is Y. People who might say N
16 here are those that are setting up dedicated Ethernet WWW/FTP
17 servers, or users that have one of the various bus mice instead of a
18 serial mouse and don't intend to use their machine's standard serial
19 port for anything. (Note that the Cyclades and Stallion multi
20 serial port drivers do not need this driver built in for them to
23 To compile this driver as a module, choose M here: the
24 module will be called 8250.
25 [WARNING: Do not compile this driver as a module if you are using
26 non-standard serial ports, since the configuration information will
27 be lost when the driver is unloaded. This limitation may be lifted
30 BTW1: If you have a mouseman serial mouse which is not recognized by
31 the X window system, try running gpm first.
33 BTW2: If you intend to use a software modem (also called Winmodem)
34 under Linux, forget it. These modems are crippled and require
35 proprietary drivers which are only available under Windows.
37 Most people will say Y or M here, so that they can use serial mice,
38 modems and similar devices connecting to the standard serial ports.
40 config SERIAL_8250_CONSOLE
41 bool "Console on 8250/16550 and compatible serial port"
42 depends on SERIAL_8250=y
43 select SERIAL_CORE_CONSOLE
45 If you say Y here, it will be possible to use a serial port as the
46 system console (the system console is the device which receives all
47 kernel messages and warnings and which allows logins in single user
48 mode). This could be useful if some terminal or printer is connected
51 Even if you say Y here, the currently visible virtual console
52 (/dev/tty0) will still be used as the system console by default, but
53 you can alter that using a kernel command line option such as
54 "console=ttyS1". (Try "man bootparam" or see the documentation of
55 your boot loader (grub or lilo or loadlin) about how to pass options
56 to the kernel at boot time.)
58 If you don't have a VGA card installed and you say Y here, the
59 kernel will automatically use the first serial line, /dev/ttyS0, as
62 You can set that using a kernel command line option such as
63 "console=uart8250,io,0x3f8,9600n8"
64 "console=uart8250,mmio,0xff5e0000,115200n8".
65 and it will switch to normal serial console when the corresponding
67 "earlycon=uart8250,io,0x3f8,9600n8"
68 "earlycon=uart8250,mmio,0xff5e0000,115200n8".

145 driver, say Y here. This includes HUB6 support, shared serial
146 interrupts, special multiport support, support for more than the
147 four COM 1/2/3/4 boards, etc.
149 Note that the answer to this question won't directly affect the
150 kernel: saying N will just cause the configurator to skip all
151 the questions about serial driver options. If unsure, say N.
153 config SERIAL_8250_MANY_PORTS
154 bool "Support more than 4 legacy serial ports"
155 depends on SERIAL_8250_EXTENDED && !IA64
157 Say Y here if you have dumb serial boards other than the four
158 standard COM 1/2/3/4 ports. This may happen if you have an AST
159 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
160 from <http://www.tldp.org/docs.html#howto>), or other custom
161 serial port hardware which acts similar to standard serial port
162 hardware. If you only use the standard COM 1/2/3/4 ports, you can
163 say N here to save some memory. You can also say Y if you have an
164 "intelligent" multiport card such as Cyclades, Digiboards, etc.

332 Support for the asynchronous serial interface (DUART) included in
333 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
334 the letter D in DUART stands for "dual", which is how the device
335 is implemented. Depending on the SOC configuration there may be
336 one or more DUARTs available of which all are handled.

392 appear as /dev/ttyATn (major 204, minor starting at 154)
393 instead of the normal /dev/ttySn (major 4, minor starting at
394 64). This is necessary if you also want other UARTs, such as
395 external 8250/16C550 compatible UARTs.
396 The ttySn nodes are legally reserved for the 8250 serial driver
