# # Serial device configuration # menu "Serial drivers" depends on HAS_IOMEM # # The new 8250/16550 serial drivers config SERIAL_8250 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. config SERIAL_8250_CONSOLE bool "Console on 8250/16550 and compatible serial port" depends on SERIAL_8250=y select SERIAL_CORE_CONSOLE ---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.

The following steps need to be completed to use the Serial MUX: 1. create the device entry (mknod /dev/ttyB0 c 11 0) 2. Edit the /etc/inittab to start a getty listening on /dev/ttyB0 3. Add device ttyB0 to /etc/securetty (if you want to log on as root on this console.) 4.

The 8250 serial port driver also uses these numbers, which means the two drivers being unable to coexist; you could not use both z85C30 and 8250 type ports at the same time. If this option is not selected, the pmac_zilog driver will use the device numbers allocated for /dev/ttyPZn. This allows the pmac_zilog and 8250 drivers to co-exist, but may cause existing userspace setups to break. Programs that need to access the built-in serial ports on powermacs will need to be reconfigured to use /dev/ttyPZn instead of /dev/ttySn. If you enable this option, any z85c30 ports in the system will be registered as ttyS0 onwards as in the past, and you will be unable to use the 8250 module for PCMCIA or other 16C550-style UARTs.
