Fw: [wl2kemcomm] Fw: [aprssig] Anyone know what DISABL is?

Guys, I forwarded the DISABL post to the wl2k yahoo group and got this reply. Now that the problem has been made aware(most telpac node operators are on that list) they will start looking into it. We had the same problem with our telpac node and it was a new kpc3+ too. We ended up using agw and agwterm with the telpac node so it all runs together and that network feature is turned off since it is in kiss mode.

I discovered this a few months ago and am sorry I haven't yet shared what I found. I can see where it can affect other applications like APRS if the TNC is used for both Telpac and the other packet apps.

A few of us ran into this issue when we purchased KPC3+ V9.1 last November. Someone was quick to blame Winlink on this "Phantom Beacon" and I assured that the Winlink apps were not the cause. Well, not directly as I later found out.....

The beacon comes from the setting for NETCALL.
The default factory value is lowercase "disabled"  >> NETCALL disabled <<

When Telpac initializes and reads the original TNC settings, it saves that setting in the registry as "disabled" . If you select "restore TNC settings on exit" in the Telpac settings, then Telpac will issue the cmd "NETCALL DISABLED" when you close the program (along with restoring all the other saved settings.) 
The TNC sees the value "DISABLED" for the NETCALL cmd and sets that value, thinking its a node alias. This turns on the NET feature in the TNC and results in the automatic beacon DISABL . I guess it only holds 6 chars for the alias.

According to a phone call with Kantronics, the only way to turn it off is with a hard reset.
cmd: restore -d 

In Telpac I just make sure "restore TNC settings on exit" is unchecked. Maybe Rick can find a way to code around this issue in a future release. But it's not his fault this happens. I am unaware of any other applications that restore settings on exit like this though. Personally, I don't think the firmware should require a hard reset to turn off any feature in the TNC, and I don't know if this is the case with the 9612 or other units.

There are other settings where you could set the value to null by using %, but I haven't tried it with NETCALL yet.

  Those running a KPC3 Plus might want to check their Network Node alias. We had the default DISABL in our Telpac node when we first set it up and it took us a while to figure out we needed to turn off the Network Node to keep it from ID'ing. From the APRS list it looks like some have telpac nodes that are sending out the node broadcast. I'm guessing some have a telpac node on the aprs frequency or other local packet frequency.
  Maybe this could be added to the telpac initialization file for the kpc3+ to automatically turn it off when it starts up telpac?
  Might be something to check out,

  I actually was able to connect to it but was able to get nothing more than a "DISABL}" out of it.  Lets assume that this is a KPC-3 with the node turned off.  What "commands" would I enter to get something out of it.  I've tryied i, h, r, ?, /help and /?.  What else could I try.  Note that I have a poor path to this station whereever it might be.

    There's a station like this in the Kansas City area, too, among other places.  Using a terminal program try connecting to it (C DISABL). Once connected, you'll probably be able to determine the station callsign with just a little searching.

      Hi All,

        Ever since I started operating APRS, I've seen this station that IDs with DISABL.  Does anyone know what this is?  Is this an old experiment long forgotten?
