    I'm quite sure Packet_Send does not touch RAM_INDEX_R. I did not
check IRP neither simulated the program (as far as i know we can't
simulate serial devices). But the point is that i tried to send the
character that will be sent to the radio via the serial port, and it works.

    This is what makes the problem strange. Isolated Packet_Send works,
and isolated the loop in the memory works too, but they do not work
together.
