if you check default dzsbot.tcl you will find these procedures on the top of the file:
Code:
proc u {} {return }; # underline code
proc r {} {return }; # reverse code
proc b {} {return }; # bold code
proc c {} {return }; # color code
proc o {} {return }; # reset attributes code
if you dont have them there, add them and everything should be fine. its much easier to do the coloring this way than the other way...
