Why do you think there's only 1 byte that can be sent?
If your data buffer is longer, bytes are sent one-by-one
serially in a packet...

look into lnp.c and you will see that both lnp_integrity_xxx
and lnp_addressing_xxx are implemented using lnp_logical_xxx,
so lnp-logical is just a lower layer of the LNP protocol.
Do you have some particular plans with your RCXs?
Pavel.
