Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OS X to manage email communication in a private way, without relying on online services (in fact, encouraging users to store email locally). It mainly features a system for mailinglist filtering, address-book integrated whitelisting, strong encryption and anonymous remailing, long-term email storage and archiving with functions for fast search and usage statistics. To accomplish all that, it makes use of solid Unix tools like Mutt, Fetchmail, Mairix, Msmtp, GnuPG, Abook, ELinks, and Mixmaster.

The program is fully scriptable via VBScript, JScript, PerlScript, or Python.
SerLooK is a KDE application for inspecting data going over serial lines. It can work as a binary terminal that sends and receives data through a defined port (Point to Point mode) and displays them on separate views. Each view can be configured to display data in hexadecimal, decimal, octal, binary, and raw ASCII. It is also possible to perform I/O through terminal emulation views and define a secondary port and monitor the traffic between two external hosts using a "Y" cable (Snooper mode).
