256 colours support like xterm or konsole have whould be nice.

I googled the "xterm 256 color extension", and find that the escape sequences used by xterm to change to 256 colors also exit in linux kernel console sequences, but they have different meanings.

FbTerm is compatible with linux kernel console sequences, it seems like supporting 256 colors in FbTerm is impossible.

Yeah, 256 colors would be really nice as there is no such terminal emulator for frame buffer available yet, and would be really useful for those trying to avoid X11.

FbTerm version 1.4 add this feature
