Crt was originally designed for the console and xterm.

Could you test with xterm?

I made some test on a Slackware 10.1 installation, with FPC 2.6.2 (just it).
On xterm and xrvt, the cursor remains visible; otherwise in the console (Ctrl-Alt-F6) it disappears correctly.
I do a quick look through the code (packages/rtl-console/src/unix/crt.pp) and I noticed that CursorOff procedure relies on ttySendStr, which makes use of the variables InCnt, InHead, InTail and OutCnt that are not initialized, while they should all start at 0.
I do not be sure whether it is related to the problem, considering the automatic initialization performed by the compiler, I would test by myself but I have problem to recompile on Linux.
Hope that helps, Marco Borsari
