In the early days of Amateur Packet Radio, it was necessary to use a
"Terminal Node Controller" (TNC) with specialized hardware.  Those days are
gone.  You can now get better results at lower cost by connecting your radio
to the "soundcard" interface of a computer and running free software.
Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder.   It
can be used stand-alone to observe APRS traffic, as a digipeater, APRStt
gateway, or Internet Gateway (IGate).    It can also be used as a virtual
TNC for other applications such as APRSIS32, UI-View32, Xastir, APRS-TW,
YAAC, UISS, Linux AX25, SARTrack, RMS Express, and many others.

The new features in this release include:

* Improved demodulator now decodes over 1000 error-free packets from WA8LMF
TNC Test CD.
* Up to 3 different audio devices at the same time.
* Reduced latency for transfers to/from soundcards. More accurate transmit
PTT timing.
* Packet filtering for digipeater and IGate.
* Data Carrier Detect (DCD) can be sent to an output line (just like PTT) to
activate a carrier detect light.
* Linux "man" pages for on-line documentation.
* New framework for applications which listen for Touch Tone commands and
respond with voice.  A sample calculator application is included as a
starting point for building more interesting applications.   For example, if
it hears the DTMF sequence "2*3*4#" it will respond with the spoken words
"Twenty Four."   No special hardware required - DTMF decoding is done in
