SDLC STUN local ack - R R 00 data from wrong address!

I've been attempting to implement SDLC STUN with limited success. With
local acknowledgement turned on I get an SDLC error in the debig and
it doesn't work, turn off local ack and it bursts into life.

Can anyone shed some light on this?

I then removed local acknowledgement and all started working ok
