dingetje>1.Post an URL where the source code (+ docs) can be found.
2. Which version of freesco you want it for.
1 - Project URLs:
<a href='http://www.rdesktop.org' target='_blank'>http://www.rdesktop.org</a> ; <a href='http://sourceforge.net/projects/rdesktop/' target='_blank'>http://sourceforge.net/projects/rdesktop/</a>
About ability runing rdesktop without X-server I have read on Russian pages
( <a href='http://elinux.org.ru/rdesktop/' target='_blank'>http://elinux.org.ru/rdesktop/</a> or <a href='http://www.wtpro.ru/rdesktop/)' target='_blank'>http://www.wtpro.ru/rdesktop/)</a>
"rdesktop.patch.gz for rdesktop, allowing to start the program without need for the X-server. For videoout the svgalib is using."
But link to rdesktop.patch.gz isn't working.
2 - Any. May be current or future. I am using 0.3.8
If the svgalib isn't accessible under FREESCO - the question is closed.
Though as a patch-file may be exist or may be not, we can forget about subject

Sorry for the "excellent" English.
