Thanks! It works pre[tty] good! :-)
I have two more questions :

Sometimes I see warning:
terminal is not fully functional.
So I can't edit kernel file mit ee - the text is shown "shifted" in their 
lines.
Must I use another terminal program to help this?

And what you can do with "headless" PC? Can you control this PC only in
command prompt? Or (may be) you can use anything like X - twm?

Thanks in advance.
