In bpq32.cfg add
TNCPORT
COMPORT=/home/pi/fbbded
TYPE=DED
STREAMS=1
APPLMASK=4
ENDPORT
This creates a DED Host mode TNC on device /home/pi/fbbded, accessible from the LinBPQ Node as Application 3. Change APPLMASK and APPLICATION line if you already use APPL 3
APPLICATION 3,FBB,,PI1LAP,LINBBS,255
This allows uses to connect to FBB. You can add the usual Call, Alias and Quality if you want to be able to access FBB directly instead of via the Node.
Change APPLMASK and APPLICATION line if you already use APPL 3
