ansistego provides terminal-level steganography for scripts and other ASCII files (ie, protection against 'cat'). It intersperses a text/script with commented ANSI codes that cause most terminals to clear sensitive lines as soon as they are written. Only a specified front text appears. The front text is embedded in the script using ANSI-cloaked comments, so that the text appears unaltered when the script is viewed with cat, but the script can be run without any decoding stage.
gtermix is a GTK+ telnet client intended for calling BBSes. It utilizes a custom VGA textmode emulating terminal widget that allows it to accurately render bulletin board systems as they were in DOS terminal programs. It currently features a GTK+ user interface, dialing directory, support for ANSI, vt100, Avatar, and TextFX terminal emulations, and proper rendering for DOS-style BBSes.
