Free serial line software for linux

slsnif is a serial line sniffer. It listens to the specified serial port and logs all data coming through it. slsnif works transparently for both the device connected to the serial port and the controlling software for this device. It operates by opening a pseudo tty (pty) and linking it to the actual serial port.
slsnif operates by opening a pty and linking it to the serial port. These are following parameters / options:
1. Serial port to open (required).
2. Name of the file to direct output to (optional, defaults to stdout).
3. Desired baudrate (optional, defaults to 9600 baud).
4. Timestamp On/Off (optional, defaults to Off).
5. Print ascii values in hex On/Off (optional, defaults to Off)
6. Print number of bytes transmitted On/Off (optional, defaults to Off).
7. Optional colors for timestamp, number of bytes transmitted and normal output.
8. Lock port On/Off (optional, defaults to On).
9. Use Unix98 ptys instead of BSD ptys (optional, defaults to BSD style).
10. Second serial port to open. If specified, this port will be used instead of a pty, thus providing an ability to log data between two serial ports.
Enhancements:
- Added ability to resynchronize ports at any time by sending a SIGUSR1 signal to slsnif. Useful for debugging applications that change port parameters mid-way, after starting the transmission. One example is pppd daemon, which sets initial parameters in the chat script, and changes them later, after chat script terminates.
- Added ability to use SYSV (Unix98) ptys instead of BSD ones (see -u and --unix98 parameters). This option can also be turned on/off from rc-file.

LibSerial provides a collection of C++ classes that allow one to access serial ports on POSIX systems like standard C++ iostream objects.

Member functions are provided for setting various parameters of the serial ports such as the baud rate, character size, flow control and others. LibSerials idea is to simplify serial port programming on POSIX systems.

When you have installed the above tools, run the following commands:

Installation:

./configure
make
make install

Note: The html documentation will not be installed by "make install". I will fix this in the future release.

Console Lines is a "Lines" game for the Unix terminal. There is no in-game help available right now, so check the README file. To move the cursor, use arrows (or jkhl), to select or to move a chip, use space. To instantly quit, use q. Console Lines requires a certain terminal size, supports a mouse (curses or GPM), and works with various ncurses libraries.
You will need an ANSI standart C compiler, GNU make, and a decent curses library that supports colors.
The current lists of operation systems tested:
Linux, glibc 2.2
Solaris 9
OpenBSD 3.8
CygWin 5
Enhancements:
- Support for smaller terminals (as small as 19x19).
- Support for terminal resize.
- Support for black and white terminals.
- Support for command line options.
- A workaround for a nasty ALTLinux/Debian GPM bug.
- Persistant high scores.
- A man page has been added.

Randomize Lines (rl) is a command-line tool that reads lines from an input file or stdin, randomizes the lines and outputs a specified number of lines. It does this with only a single pass over the input while trying to use as little memory as possible.
I wrote rl in my spare time mainly to be able to select a random audio file to play when my toast is done (script in combination with find and sleep). Another reason was to familiarize myself with autoconf and friends.
The most recent version of this page can be found at http://ch.tudelft.nl/~arthur/rl/.
Warning: rl is software in development. The command line options and default behavior may change between releases.
Another Warning: I have mostly lost interest in this project and am not planning on doing much development on it any more. I will however still accept patches and fix important bugs (this more or less contradicts the previous warning).
Enhancements:
- A dangerous example was removed from the manual page and was replaced by several benign ones.

Beyond the Red Line project is a stand-alone total conversion for the award-winning Freespace 2 released by Volition and Interplay for the PC. It is based on the popular new tv-show Battlestar Galactica. No, not the one from the 70s.
Will I need Freespace 2 to play it?
No, Beyond the Red Line is a stand-alone conversion and will not require Freespace 2. All you need for playing will be included in the download.
Is it free?
Absolutely. The game is made by fans for the fans, no profit is being made from any part of the project. Although we could use some pizzas and coke to keep our mortal bodies running.
That about covers it... a BSG total conversion of FS2 that has just released a demo version. it plays really well and looks amazing. a must for any BSG fan.
Enhancements:
- This demo contains spoilers for the second season of BSG, so if you havent seen that season yet you should pass on this game for now.

Virtual Console init is an /sbin/init clone for virtual consoles. It is very easy to set up and use because it has no configuration files.
It is very small and has builtin getty, login, klogd, and slogd. Virtual Console init is suitable for embedded systems and home Linux boxes.
This is a new kind of "init" that only works for the virtual console, so dont try it to login from a serial line. The idea is having a very simple init for home Linux systems (although it could work on other systems as well, who knows...), allowing for a simpler and cleaner configuration. It is useful too in embedded systems or tiny boot disks (maybe as a complement for "busybox"). In other words: it works for me, I use it and Im releasing it in the hope of it being useful for others.
The binary itself doesnt accept parameters, so lets go directly to the behaviour... It must be run by "root" and have PID 1, so dont try to run it yourself, it wont work... You should install it under "/sbin/init", and the kernel will run it automatically at boot.
Take into account that this "init" has both the "getty" and "login" parts built-in, not as separate binaries. This means that if you have a server or another binary which needs "/bin/login", it probably WONT WORK. The sysklog system (kernel logger and system logger, "klogd" and "slogd") are built-in, too. You dont need sysklogd or equivalent, unless you want some feature of them... In that case, you can disable the builtin system.
Enhancements:
- vcinit is now licensed under the GPLv2 only, and not necessarily any later version of the GPL.
