I haven't done this myself, but I have seen explanations before. Kernel recompilation with "support console on serial port" is only needed in order to be able to see boot messages on a serial terminal. A serial port driver must be installed in order to use a serial port. Almost all kernels are compiled with serial support enabled, either compiled-in or as a module. With a serial driver installed, you can specify the corresponding serial port devices to software that uses serial ports. One such program is getty, controlled by the "init" process according to the settings in /etc/inittab. If you don't want boot messages to be spit out the serial port, then you don't want to enable "console on serial port" in the kernel. (remove bootloader "append=/dev/ttyS0"). If you don't want to see login messages on the serial port, then you want to disable getty on that port in inittab. I am not clear on how the append kernel option affects this, but I think it is related to redefinition of /dev/console by the kernel. Look at the Serial howto and the Text terminal howto at http://www.linuxdog.org, and /usr/src/linux/Documentation/serial-console.txt. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
