Hi,
By default this capability is not enabled, but after some researching of the
source code (winsup/cygwin/fhandler-console.cc) I found that it can be
supported. This is what I tried and doesn't work properly, start with an
empty console:
bash$ echo -e '\E[10;0Hhello\E[11;20r\E15;0H\EM\E[0;0H'
The result should be that hello is displayed on line 10, and a scroll on
line 11 through 20, but no noticeable effect because these lines are empty.
The actual result is that hello is displayed twice: once on line 10, once on
line 11. My 'infocmp -Cr' looks like this:

I am doing this because I am trying to do split screens on a remotely run
screen on a linux system. My $TERM is cygwin, locally and remotely, and with
the same cygwin terminfo file. When the cs capability is removed, it works
'correctly' but all lines are jumping up and down. This jumping is due to
screen scrolling the entire screen, then redrawing the affected split
regions that didn't want scrolling.
Thanks in advance,
Micha.
