Here is a description of a common routine, that is necessary to set up a serial console.

unfortunately this way is not for you. Then you need to find second node with a serial port on it.This node will be used to collect logs from your primary mashine. Further you need to acquireso-called null modem cable and it must be long enough to connect two mashines in question.

Ok, suppose, that preliminary operations above are performed Then you need to find second node with a serial port on it.This node will be used to collect logs from your primary machine. Further you need to acquireso-called null modem cable and you it must be long enough to connect these two machines. === Software setup === ==== Sending side ====

 For example , in GRUB boot loader it looks like such strings in configuration file <tt>/boot/grub/grub.conf</tt> it looks like this in :

Kernel loaded with such parameters will send all kernel messages to /dev/ttyS0 (first serial port, a.k.a. COM1). If you have several ports, make sure that your null modem cable is connected to the appropriate port. ==== Receiving side ====On the second node you should turn on run any software that can log from /dev/ttyS0. 

==== Port setup ====One more important thing. 115200 in the example above is the rate of emiting emitting port. Also recieving Recieving port must also work at equal the same rate.To For example, to tune ttyS0 rate use stty programlike this:
