How much overhead does that timer interrupt take when nothing is being received? I was wondering if it would be possible to make the RX pin an interrupt and not start the timer until the first IR state change occurs. That way the timer consumes no overhead until it is actually needed. Once a complete character is received, the timer could be stopped, or the main program could decide when to shut down the timer (such as after a sequence of commands was received, or a long enough period of quiet was observed).
