Serial Console

• Kernel configuration:
  • in make menuconfig (of make xconfig)
    • "Character devices" -> "Virtual terminal" -- Y
    • "Character devices" -> "Support for console on virtual terminal" -- Y
    • "Character devices" -> "Standard/generic (dumb) serial support" -- Y
    • "Character devices" -> "Support for console on serial port" -- Y
  • make dep; make clean; make bzImage; install the new kernel

• LILO:
  • in /etc/lilo.conf add:

    	serial=0,9600n8
    	append="console=tty0 console=ttyS0,9600"
    

  • reinstall lilo with 'lilo' as root

• /dev: as root do:

  	cd /dev
  	rm -f console tty0
  	mknod -m 622 console c 5 1
  	mknod -m 622 tty0 c 4 0
  
  	rm -f /etc/ioctl.save       
  

• finally:
  • in the end of /etc/inittab add:

    	S0:12345:respawn:/sbin/getty ttyS0 DT9600 vt100 
    

  • if you want to be able to connect as root from the serial console to the end of file /etc/securetty add

    	ttyS0
    

• now reboot with the new kernel and enjoy.
