I have also been reading a little about AX.25 and at some point I think I would like to have Xastir and APRX both running using AX.25. It's my understanding that AX.25 makes the connection to the APRS-IS and the two applications would use that connection, correct? Or is AX.25 only for the TNC to be shared and each application still makes its own connection to the APRS-IS? Do packets also get passed between the two applications ? What about when one application sends a packet to the TNC, does it also come back in to the other application? I'm trying to get the big picture here as to how all this works together.
Ok, I'll take a stab at the rest of your questions Tom didn't cover. AX.25 is not used for the APRS-IS connection. It's used when talking to a TNC that is in KISS mode. Or a soundcard device set up as a KISS port. What AX.25 will allow you to do is share a port across multiple bits of software. I'm not sure about the packets sent from one app to the TNC being seen by other apps. Perhaps. Give it a shot and see. As far as multiple connections to the APRS-IS servers: If you run your own server locally, you can connect it to the APRS-IS, then connect all your other apps to your local server. Xastir does have server ports that you can enable, but they're not the full-service ports you'd find an JavaAprsServer or similar. They're good for hooking multiple Xastir's together, possibly feeding off the same APRS-IS connection, but don't provide filtering. -- Curt, WE7U. http://wetnet.net/~we7u "Lotto: A tax on people who are bad at math." - unknown "Windows: Microsoft's tax on computer illiterates." - WE7U. _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
