CONFIG_SERIAL_8250: 8250/16550 and compatible serial support

General informations

The Linux kernel configuration item CONFIG_SERIAL_8250 has multiple definitions:

8250/16550 and compatible serial support found in drivers/serial/Kconfig

The configuration item CONFIG_SERIAL_8250:

Help text

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 serial. [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.
