[aprssig] DIGI_NED 0.3.5 for embedded systems

[scott at opentrac.org]

Something that's not a PC.  PICs, single-board computers, and so on.
Usually something without a full platform OS like Linux or Windows.

For Digi_Ned, this is an important step to make it usable on small devices
like the Linksys WRT54GS wireless router, or the ARM7-based TNC I'm working
on.  I know you've done work with PICs, and you've probably done programming
on a PC, too, so you can appreciate the differences.  You've got much less
processing power and memory to deal with, little if any memory management,
and often no file system.

Fortunately Digi_Ned looks to be pretty cleanly written, and it's in C -
probably the easiest language to port between devices.  Except for Java -
haven't done any embedded Java myself, but we've got a couple of Java
zealots here and I know I'm going to hear about if I don't mention it now.

Thanks info, Henk. It would be most useful if it were added, as it gives
nice cross OS capabilities and AGWPE is a wonder to behold...I've used it
for years as a TNC manager (I'm not interested in sound card tnc's), and it
does a wonderful job of it.

I was able to reprogram our local ui-digi firmware based digi box from my
wireless laptop this morning using agwTerminalTCP....the laptop running it
went wireless to my AGWPE PRO core running on an XP machine in the basement
and the two tnc's connected to it are seen as local to the laptop. Quite
amazing. Xastir uses those same two tnc's, as does UI-View32, UISS and
several other programs, even remotely. The ability to use digi_ned, the
mother of all digi-peating programs, on the Xastir machine using the AGWPE
hooks would be a real asset for us.

Thanks for at least considering it...it will help us further improve the
network.

73,

...hasan, N0AN
