Codec 2 is an open source (LGPL licensed) speech codec for 3200 bit/s and below.

TCPSER turns a PC serial port into an emulated Hayes compatible modem that uses TCP/IP for incoming and outgoing connections. It can be used to allow older applications and systems designed for modem use to operate on the Internet. TCPSER supports all standard Hayes commands, and understands extended and vendor proprietary commands (though it does not implement many of them). TCPSER can be used for both inbound and outbound connections.

The Arduino Uno (http://arduino.cc/) is an open source hardware micro- controller designed primarily for prototyping and experimentation. Although the devel/arduino port already exists for programming the device, it will not work properly with the newest Arduino hardware. Previous versions of the Arduino used an FTDI USB to Serial interface. The newest Arduino (beginning with the Uno) uses an on-board ATMel 8U2 controller to emulate a USB to Serial interface with its own custom Vendor ID and Hardware ID. As a result, NONE of the existing FreeBSD USB to serial drivers can work with it. This kernel driver supplies the necessary kernel support for the Arduino Uno on FreeBSD. Additionally, some 'ACM' USB Serial devices may work with this driver by manually adding their Vendor ID and Product ID combination to files/ids.txt Official web site

Allows access to Telldus Tellstick USB dongles for communicating with 433MHz devices in your home. Provides "telldusd", the daemon which keeps track of your tellstick devices. Through a UNIX socket, the sensors and devices can be used/ controlled from the command line tool "tdtool", or via the libtelldus-core C client library.

xnec2c is a GTK+ graphical interactive version of nec2c. It incorporates the nec2c core which it uses for reading input files and calculating output data, but it does not need and indeed does not produce an output file by default. Graphs of frequency-related data and the current or charge distribution evolve as the frequency loop progresses, and radiation patterns (far and near field) are sequentially drawn for each frequency step.

Base64 is a command line utility which encodes/decodes arbitrary binary information in the base64 format used by MIME-encoded documents, such as electronic mail messages with embedded files (RFC 1341 and successors).

dumpasn1 is an ASN.1 parser which dumps the contents of an ASN.1-encoded file, as well as interpreting the OIDs contained in the file into human-readable format. Dumpasn1 is intended for examining the contents of PKI certificates and comes with a full list of security-related OIDs, but can be easily extended to parse other OIDs as well.

Tools for the conversion to and from UTF-8 Unicode encoding. Note that RFC-2277 mandates that all "protocols" MUST handle UTF-8 properly. - utrans converts text files created using any 8-bit character map into UTF-8; - uhtrans converts UTF-8 files into 7-bit ASCII with anything else formatted as an HTML-style tags, e.g. Ӓ (decimal); - hutrans converts 7-bit ASCII files with HTML-style tags, to UTF-8, thus complementing the functionality of hutrans; - ptrans converts UTF-8 files into 8-bit text using any 8-bit character map, thus complementing utrans. Additionally, tuc is installed if not found. Tuc converts text files between the DOS/Windows and the Unix formats. This port depends on ports/converters/libutf-8. Further details: RFC 2277, and RFC 2279.

ical2html takes an iCalendar file and outputs an HTML file showing one or more months in the form of tables.

A library of C routines for the conversion of Unicode to UTF-8 and back. The library can also be used to convert the 31-bit UCS-4 mappings to UTF-8 and back.
