I m reading the following websites: An article called Serial consoles and console drivers by Alassandro Rubini at http://www.linux.it/~rubini/docs/sercons/sercons.html the serial driver Wiki at : http://www.linux-mips.org/wiki/Serial_Driver_and_Console and links given on this wiki.. However I havent found a resource that talks about these two processes, early serial console initialisation and invocation of the serial driver, in enough detail to give an idea about the processes set into action when messages are put out to the console.. Can you point me to any other useful links on this issue? Thank you. Regards, Ashlesha.
