x5250 has reached it's first milestone: version 0.5! This milestone is feature complete with tn5250 version 0.16.5. But there is more than that. Some of the features of x5250:
Version 0.4.8:
x5250*redcolor : darkred x5250*greencolor : lightgreen x5250*bluecolor : aquamarine x5250*blackcolor : black x5250*whitecolor : white x5250*yellowcolor : gold x5250*turquoisecolor : darkgreen x5250*pinkcolor : pinkFor people with black and white or grayscale display (are there any of those left?) you can use the foreground and background defaults. The individual color defaults override the foreground and background defaults so greencolor will override whatever you may have for foreground.
Note for users who get odd colors: Some unix installations appear to override whatever defaults exist in $HOME/.Xdefaults and force the foreground and background to be some odd color. Notably Fedora Core 2 seems to do this. This might be a result of launching x5250 from gnome-terminal. Either launch x5250 from a true xterm or do 'xrdb -remove' before starting x5250. You can also start x5250 from the Run... or similar menu.
