hi everybody.
in /kernel/lnp.c
there is a function called lnp_receive_packet.
here im trying to insert a function that will display whatever came in
the data field when lnp_receive_packet was called.
(interested in seeing everything, including headers,etc)
i have made it so that it will only display the data when i press the
view button.
anyways it compiles fine and i get it to download to the RCX, but when i
try to download another "user" program to the rcx
i always get "error deleting program"
so.heh...i guess im missing something pretty obvous here, but i cant
seem to figgure it out.
any advice greatly appriciated

| (...) Posting your code would help a lot :-). lnp_receive_packet() is called after the integrity layer has verified the checksum from an interrupt handler. So your code should be short e never call functions that wait or may cause a task switch. dll (...) (24 years ago, 1-Mar-01, to lugnet.robotics.rcx.legos)
