10.1. Linux kernel version 2.5
Kernel version 2.5 is under active development, so this
section may be out of date. Version 2.5 includes support for the
console to a serial port attached to a USB dongle. The
-dj patch to the version 2.5 kernel has a
rewritten console layer; it is not known if the rewritten layer
effects the user-space use of the serial console.
When configuring the kernel set the following configuration
parameters:
This should set the following configuration parameters in
/usr/src/linux/.config.
If you also want to use a serial port attached to a
USB bus, then in addition to the usual
USB configuration, configure the kernel to load
the USB console driver and one of the
USB serial dongles (our example uses the generic
serial dongle).
This should set the following configuration parameters in
/usr/src/linux/.config
You should also configure the kernel without the magic
SysRq key, as described in Section 9.9.
