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

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.

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

"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".

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.

external 8250/16C550 compatible UARTs.
396
The ttySn nodes are legally reserved for the 8250 serial driver
397
but are often misused by other serial drivers.

To use this, you should create suitable ttyATn device nodes in
400
/dev/, and pass "console=ttyATn" to the kernel.
