I am implementing the stmt "rc=lnp_addressing_write()" in a while loop until (rc
!= 0). Receiving unit sends an ack which is treated by lnp_addressing_write()
as a data collision w/rc= -1. It works ok as long as a reflection or actual
collision does not occur. Need a more robust sol'n. It appears that acks are
ignored in lnp_receive_packet() since length < 2. So how to guarantee delivery
?
