PC side:
#define MY_PORT 8
#define DEST_HOST 0
#define DEST_PORT 0
#define DEST_ADDR (DEST_HOST << 4 | DEST_PORT)

i am trying to send an "int data[10]" array (all in all 40 bytes), but
when i do the
result = lnp_addressing_write(data,len,DEST_ADDR,MY_PORT);
the result retuns an TX_FAILURE indicating a collision.
i can see on the LCD display on the RCX that it starts recieving , but
that is only for a fraction of a second.

Have you set up a packet handler on the RCX before sending this? I would
guess that if there isn't one, you'll run into something like TCP's
"connection refused", which might be what you're seeing. Otherwise, I
assume that other LNP stuff (e.g. dll) works under the same conditions? If
neither of those are in the right direction, can you code up a very simple
test case that fails, and either send it to me or post it somewhere?
Looking at the whole thing might help.
