How about this? pd, thoughts?
This code is just the rate limiter code.
Today the code says "have I reached the number of characters output based on
my baud rate that indicates I need to pause a bit?". And pausing after 0
characters has been output ma

Program terminated with signal SIGFPE, Arithmetic exception.
