+          This selects whether you want to include the driver for the standard
+          serial ports.  The standard answer is Y.  People who might say N
+          here are those that are setting up dedicated Ethernet WWW/FTP
+          servers, or users that have one of the various bus mice instead of a
+          serial mouse and don't intend to use their machine's standard serial
+          port for anything.  (Note that the Cyclades and Stallion multi
+          serial port drivers do not need this driver built in for them to
+          work.)
+
+          To compile this driver as a module, choose M here: the
+          module will be called 8250.
+          [WARNING: Do not compile this driver as a module if you are using
+          non-standard serial ports, since the configuration information will
+          be lost when the driver is unloaded.  This limitation may be lifted
+          in the future.]
+
+          BTW1: If you have a mouseman serial mouse which is not recognized by
+          the X window system, try running gpm first.
+
+          BTW2: If you intend to use a software modem (also called Winmodem)
+          under Linux, forget it.  These modems are crippled and require
+          proprietary drivers which are only available under Windows.
+
+          Most people will say Y or M here, so that they can use serial mice,
+          modems and similar devices connecting to the standard serial ports.

+        ---help---
+          If you say Y here, it will be possible to use a serial port as the
+          system console (the system console is the device which receives all
+          kernel messages and warnings and which allows logins in single user
+          mode). This could be useful if some terminal or printer is connected
+          to that serial port.
+
+          Even if you say Y here, the currently visible virtual console
+          (/dev/tty0) will still be used as the system console by default, but
+          you can alter that using a kernel command line option such as
+          "console=ttyS1". (Try "man bootparam" or see the documentation of
+          your boot loader (grub or lilo or loadlin) about how to pass options
+          to the kernel at boot time.)
+
+          If you don't have a VGA card installed and you say Y here, the
+          kernel will automatically use the first serial line, /dev/ttyS0, as
+          system console.
+
+          You can set that using a kernel command line option such as
+          "console=uart8250,io,0x3f8,9600n8"
+          "console=uart8250,mmio,0xff5e0000,115200n8".
+          and it will switch to normal serial console when the corresponding
+          port is ready.
+          "earlycon=uart8250,io,0x3f8,9600n8"
+          "earlycon=uart8250,mmio,0xff5e0000,115200n8".
+          it will not only setup early console.

-        tristate "8250/16550 and compatible serial support"
-        select SERIAL_CORE
-        ---help---
-          This selects whether you want to include the driver for the standard
-          serial ports.  The standard answer is Y.  People who might say N
-          here are those that are setting up dedicated Ethernet WWW/FTP
-          servers, or users that have one of the various bus mice instead of a
-          serial mouse and don't intend to use their machine's standard serial
-          port for anything.  (Note that the Cyclades and Stallion multi
-          serial port drivers do not need this driver built in for them to
-          work.)
-
-          To compile this driver as a module, choose M here: the
-          module will be called 8250.
-          [WARNING: Do not compile this driver as a module if you are using
-          non-standard serial ports, since the configuration information will
-          be lost when the driver is unloaded.  This limitation may be lifted
-          in the future.]
-
-          BTW1: If you have a mouseman serial mouse which is not recognized by
-          the X window system, try running gpm first.
-
-          BTW2: If you intend to use a software modem (also called Winmodem)
-          under Linux, forget it.  These modems are crippled and require
-          proprietary drivers which are only available under Windows.
-
-          Most people will say Y or M here, so that they can use serial mice,
-          modems and similar devices connecting to the standard serial ports.

-        ---help---
-          If you say Y here, it will be possible to use a serial port as the
-          system console (the system console is the device which receives all
-          kernel messages and warnings and which allows logins in single user
-          mode). This could be useful if some terminal or printer is connected
-          to that serial port.
-
-          Even if you say Y here, the currently visible virtual console
-          (/dev/tty0) will still be used as the system console by default, but
-          you can alter that using a kernel command line option such as
-          "console=ttyS1". (Try "man bootparam" or see the documentation of
-          your boot loader (grub or lilo or loadlin) about how to pass options
-          to the kernel at boot time.)
-
-          If you don't have a VGA card installed and you say Y here, the
-          kernel will automatically use the first serial line, /dev/ttyS0, as
-          system console.
-
-          You can set that using a kernel command line option such as
-          "console=uart8250,io,0x3f8,9600n8"
-          "console=uart8250,mmio,0xff5e0000,115200n8".
-          and it will switch to normal serial console when the corresponding 
-          port is ready.
-          "earlycon=uart8250,io,0x3f8,9600n8"
-          "earlycon=uart8250,mmio,0xff5e0000,115200n8".
-          it will not only setup early console.
