[aprssig] DIGI_NED 0.3.5 for embedded systems

[hasan schiers]

Henk,

I am running Xastir on a spare machine that uses the AGWPE PRO on one of my 
WinXP machines (talks to it via the network, and AGWPE PRO manages my TNC's)

Is there a way to run this new DIGI NED on the Debian Linux machine, side by 
side with Xastir, such that it becomes my "DIGI"...if so, I can use its 
outstanding rules based digi management instead of the ui-view32 machine 
which is also connected to AGWPE PRO.

tnx,

hasan, N0AN
