No, I meant lnp_logical_write, which is called from lnp_addressing_write.
lnp_logical_write is not within the file lnp.c, which I guess you link into
your app. This function is supposed to actually write to the serial device
communicating with the RCX. Depending on the serial port initialization
this might block. What code do you use to talk to the serial port?
