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, BPQ32,
Outpost PM and many others.

+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, BPQ32, 
+Outpost PM and many others.
