Free pin software for linux

Pin is package info searches the System (rpm -pi, -ql) and the SuSE table of contents file from the CD for a item.

The table of contents file is on the first SuSE CD (ARCHIVES.gz)

Parapin library makes it easy to write C code under Linux that controls individual pins on a PC parallel port.
This kind of control is very useful for electronics projects that use the PCs parallel port as a generic digital I/O interface.
Parapin goes to great lengths to insulate the programmer from the somewhat complex parallel port programming interface provided by the PC hardware, making it easy to use the parallel port for digital I/O. By the same token, this abstraction also makes Parapin less useful in applications that need to actually use the parallel port as a parallel port (e.g., for talking to a printer).
Parapin has two ``personalities: it can either be used as a user-space C library, or linked as part of a Linux kernel module.
There is also a device driver that provides access to the kernel module from user-space, allowing the administrator to use filesystem permissions to control access to the port.
Parapin was written with efficiency in mind, so that Parapin can be used in time-sensitive applications.
Using Parapin should be very nearly as fast as writing directly to the parallel port registers manually.
Parapin provides a simple interface that lets programs use pins of the PC parallel port as digital inputs or outputs. Using this interface, it is easy to assert high or low TTL logic values on output pins or poll the state of input pins.
Some pins are bidirectional--that is, they can be switched between input and output modes on the fly.
Parapin was originally written by Jeremy Elson while at the University of Southern Californias Information Sciences Institute. The original work was supported by DARPA under grant No. DABT63-99-1-0011 as part of the SCADDS project, and was also made possible in part due to support from Cisco Systems. It is freely available under the GNU Library Public License (LGPL).
Current maintenance of Parapin is coordinated by Al Hooton, who also wrote the device driver interface. This work is supported by a very understanding spouse and quite a lot of black pekoe tea.
Enhancements:
- Fixes for two important bugs.
- A build infrastructure has been added for building/maintaining multiple language bindings on top of parapin.
- This is the first formal release of Pedro Wernecks Python language binding.

PPSkit is an implementation of nanosecond time and a PPS API for the Linux kernel, as described by RFC-1589 and RFC-2783.
This collection contains:
0) A new kernel that keeps time in nanoseconds (instead of microseconds). These changes come along with several other improvements and cleanups.
1) Extensions and bugfixes for adjtimex() to adjust the value of `tickadj (defaults to 500/HZ). This can be useful when the adjtime() doesnt work at all or is too slow (1ms on Alpha architecture, 0.5ms per second by default on i386 architecture).
2) New code to support PPS (pulse-per-second) clock synchronization in the kernel (also known as ``nanokernel #4).
3) Example implementation for the serial driver (implements detection of pulse on DCD pin). The implementation uses the new PPS API for portability and nanosecond accuracy.
4) Some utilities and documentation files (like this).
Enhancements:
- The kernel patches were updated to support more recent 2.4 kernels.
- GCC 4.0.x support was fixed.

The SvxLink project aim to develop a flexible general purpose voice services system for ham radio use. The svxlink server consists of a core that handles the connection to the tranceiver.
The transceiver audio is connected to the PC through the sound card and the PTT is controlled by a pin in the serial port. The core can be configured to act as a repeater controller or to operate on a simplex channel.
The voice services are loaded into the core as plugins called modules in SvxLink lingo. Existing voice services are: Help - a help system, Parrot - a module that plays back everything you say, EchoLink - connect to other EchoLink stations and TclVoiceMail - a simple voice mail system. The project also includes an EchoLink client GUI application (Qtel).
EchoLink is an amateur radio invention (well actually it is just a modified verison of IP telephony) to link radio transceivers together over the Internet. You must have an amateur radio license to use it. The original EchoLink software can be found at http://www.echolink.org/.
However, this software only support the Windows operating system and it is closed source. SvxLink is FREE software released under the GPL license.
Qtel is only an EchoLink client program. It does not have the sysop mode. That is, it can not be connected to a transceiver and act as a link. For the latter, use the svxlink server.
Enhancements:
- Support for remote receivers linked over the Internet has been added.
- To be able to use multiple receivers, a simple signal strength detector was implemented.
- CTCSS tone transmit has been implemented and the CTCSS squelch detector has been improved, which makes it possible to run SvxLink with the squelch open.
- DTMF muting and squelch tail elimination has been added, and there are a couple of other changes and bugfixes.

PUD GNU/Linux LXDE is a mini Linux live CD which takes up under 200MB, and with support for Traditional Chinese (zh_TW).
The main purpose is to provide a complete Linux desktop with many popular applications and tools, yet remain small and simple to operate.
This release is made for LXDE, the Lightweight X11 Desktop Environment, and using the latest stable code from build-livecd and PUD GNU/Linux.
Main features:
- Pre-configured LXDE desktop
- This LiveCD is based on PUD, so except the full-featured Live CD, it also included the newest lxpanel, lxsession, pcmanfm and integrated with those configurations from the LXDE guide, to provide an easy to use, lightweight and fast Desktop.
- Multi-Language Support
- As you can see, English, both Simplified and Traditional Chinese are fully supported by LXDE LiveCD.

pcsc-ctapi-wrapper library provides a CTAPI-interface to any PC/SC compatible smartcard reader.
You can use any PC/SC smartcard reader with applications which support only CTAPI.
Enhancements:
- This is the first release of pcsc-ctapi-wrapper which implements all important features for smartcard readers.
- For example, it works with HBCI homebanking software.
- PIN-keyboards of smartcard readers are not supported yet.

Transec is a Java taglib component that provides a secure PIN/TAN/password input via untrusted, insecure Web browsers.

Only images and coodinates are transferred to the browser.

TRANSEC is a virtual keyboard that can prevent spyware or troyan attacks. Transec is self-explanatory and can be easily used. PIN- and TAN-inputs are visible only for the user.

The user enters his/her data using a virtuall keyboard instead of the common keyboard.

Though Interception of input data is almost impossible.

If at all, only by intercepting all mouseclicks plus each single referred picture an agressor could be succesfull, because the virtual keybourd is randomly rotated after each entry.

This inputmodule can be easily integrated as JSP-taglib in each JSP-Software. It may need minimal adaption (colors etc.).

Pcb is a handy tool for the X Window System to design printed circuit boards. All coordinate units are 1/1000 inch. A layout consists of lines, arcs, polygons, elements (lines, pins and arcs), vias, and text information seperated into several layers.

Each of them is identified by a unique name and color (if supported by your display). SMD circuits are also supported. Eight layers are supported, in addition to a silkscreen layer. Visibility of pins and SMD pads and vias is controllable.

All files are 7-bit ASCII, and can be preprocessed with any Unix command that writes its results to stdout (GNU m4 is required). Zooming, unlimited undo, and unlimited redo are supported.

Pcb is intended to be a simple tool without memory and time consuming features like autorouter and autoplacement. Layout related settings are saved together with the data.
