13 depends on (BROKEN || !(SPARC64 || SPARC32))
14 select SERIAL_CORE
15 ---help---
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
23 work.)
24
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
30 in the future.]
31
32 BTW1: If you have a mouseman serial mouse which is not recognized by
33 the X window system, try running gpm first.
34
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.
38
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.

43 bool "Console on 8250/16550 and compatible serial port"
44 depends on SERIAL_8250=y
45 select SERIAL_CORE_CONSOLE
46 ---help---
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
51 to that serial port.
52
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.)
59
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
62 system console.
