In kdbg proces xterm is opening in fifo and i try too put yours lines and 
nothing changed.
Now i found, and problem is in xterm.
1) start xterm with this "xterm -geometry 130x30" in this opened xterm  i put "echo 
$LINES - $COLUMNS" and show properly values
2) now i start xterm with program "xterm -geometry 130x30 -e sh -c 'echo $LINES - $COLUMNS;sleep 
20'" and a i didn't get any values. Parameter LINES & COLUMNS now not setting. Same problem is 
in konsole with this "konsole -e sh -c 'echo $LINES - $COLUMNS;sleep 20'"
