      I've been using the Serial KISS TNC

      The laptop I'm trying to hook to it doesn't have AX25 configured (yet)
      - I've got another station running in that manner just as a soundmodem
      and it works great. Is it possible to use AX25 and NOT have to use a
      "soundmodem" ?? I really like to simplicity of just hooking up the USB
      dongle to the serial cable for the TNC and I'm done. I only plan on
      using Xastir for the time being. I would be interested in learning
      more about this mode. Does the Tracker2 not run in KISS mode then??

      This is how I've been running it - I've tried it with and without the
      box checked; and have since learned to leave it unchecked as you've

      I'm not familiar with the TNC-X.

      Thanks for your reply Curt!
