I run version 0.65 of the firmware and I thought it supports all forms of packet radio, APRS beaconing, Winlink, UI-View, Xastir and WinTNC. Most of packet radio with KISS TNCs depends on the application running on the computer. There were some versions a while back that did specific things so maybe I'm just off my rocker.
