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 serial.
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
67 tristate "8250/16550 PCMCIA device support"
68 depends on PCMCIA && SERIAL_8250
70 Say Y here to enable support for 16-bit PCMCIA serial devices,
71 including serial port cards, modems, and the modem functions of
72 multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
73 credit-card size devices often used with laptops.)

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

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

113 depends on SERIAL_8250_EXTENDED && !IA64

116 standard COM 1/2/3/4 ports. This may happen if you have an AST
117 FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
118 from <http://www.tldp.org/docs.html#howto>), or other custom
119 serial port hardware which acts similar to standard serial port
120 hardware. If you only use the standard COM 1/2/3/4 ports, you can
121 say N here to save some memory. You can also say Y if you have an
122 "intelligent" multiport card such as Cyclades, Digiboards, etc.
124 config SERIAL_8250_SHARE_IRQ
125 bool "Support for sharing serial interrupts"
126 depends on SERIAL_8250_EXTENDED
128 Some serial boards have hardware support which allows multiple dumb
129 serial ports on the same board to share a single IRQ. To enable
130 support for this in the serial driver, say Y here.
132 config SERIAL_8250_DETECT_IRQ
133 bool "Autodetect IRQ on standard ports (unsafe)"
134 depends on SERIAL_8250_EXTENDED
136 Say Y here if you want the kernel to try to guess which IRQ
137 to use for your serial port.
139 This is considered unsafe; it is far better to configure the IRQ in
140 a boot script using the setserial command.

718 Even if you say Y here, the currently visible framebuffer console
719 (/dev/tty0) will still be used as the system console by default, but
720 you can alter that using a kernel command line option such as
721 "console=ttyCPM0". (Try "man bootparam" or see the documentation of
722 your boot loader (lilo or loadlin) about how to pass options to the
723 kernel at boot time.)

875 tristate "Digi International NEO PCI Support"
879 This is a driver for Digi International's Neo series
880 of cards which provide multiple serial ports. You would need
881 something like this to connect more than two modems to your Linux

883 supports PCI boards only.
884 If you have a card like this, say Y here and read the file
