I would like to know how it is possible to use the screen from this program version of sc singleclick

from this topic http://forum.ultravnc.fr/index.php?topic=68.msg380
with the settings of this program

from this topic [topic=4068][/topic].
Why would I like to do this?
For encryption and also to make it easier for the person (the client) to connect to the helpdesk. He will only have to enter a number on one available field, which is much less confusing than this

So what would I have to change/add in the helpdesk.txt of this to connect through the echo-server.

Thanks
Betsy.
