Okay thanks, but what should I use (on Solaris)?

I tried:

  $ TERM=xterm-256color python test_userscreen.py

and get the same result. Trussing it shows that it is using:

  /usr/gnu/share/terminfo/x/xterm-256color


In a previous reply you mention:

 "I have a to-do note dealing with "xterm+256color" on Solaris (it's
 completely wrong)."


so that's probably the problem. Is there anything I can do to help you 
fix that?

In the meantime, what would you suggest we can use (on Solaris)
instead, to get the desired result?

I also tried:

$ TERM=sun python test_userscreen.py

but that complained that there wasn't color support.
