The Linux Serial Sniffer allows you to sniff serial data up to 460Kbs via a Comtrol RocketPort or to 115Kbs using the standard ttyS0 and ttyS1 ports. Sniffed output can be captured to disk or displayed directly on screen. A user filter is included to assist specific customisation. The Linux Serial Sniffer can selectively operate in either a "ghost mode" where there is no data flow time impediments, or via a "capture and forward mode", where the user can flexibily intercept and extend the data stream to suit from either direction.
C-Kermit is a combined serial and network communication software package offering a consistent, medium-independent, cross-platform approach to connection establishment, terminal sessions, file transfer, character-set translation, numeric and alphanumeric paging, and automation of communication tasks. Recent versions include FTP and HTTP clients as well as an SSH interface, all of which can be scripted and aware of character-sets. It supports built-in security methods, including Kerberos IV, Kerberos V, SSL/TLS, and SRP, FTP protocol features such as MLSD, and source-code parity with Kermit 95 2.1 for Windows and OS/2.
Mrxvt (previously known as materm) is a multi-tab X terminal emulator based on rxvt/aterm. It supports multiple tabs, runtime dynamic tab title, pseudo-transparent backgrounds, user-supplied background images (JPEG, PNG, or XPM), background color tinting, text shadows, NeXT/rxvt/xterm/SGI style scrollbars, XIM, multiple languages (Chinese, Korean, and Japanese) and logging. It is lightweight and fast, and only depends on Xlib.
conexus is a generalized C++ I/O library that includes network support for IPv4 and IPv6 sockets, serial/TTY communications, kernel message queues, pipes, and files. Objects use sigc++ for signaling property changes and other information. Sub-libraries include conexus-gtkmm (provides a set of gtkmm widgets), conexus-dbus (provides dbus support for endpoints), conexus-nspr (provides NSPR endpoints), conexus-nss (provides NSS endpoints), and conexus-ssl (provides OpenSSL endpoints).
xtermcontrol enables dynamic control of XFree86 xterm properties. It makes it easy to change colors, titles, fonts, and the geometry of a running xterm, as well as to report the current settings of the properties. Window manipulations such as (de)iconify, raise and lower, maximize and restore, and reset are also supported. It also lets advanced users issue any xterm control sequence.
