That's a binary 7 code. If you are using a serial comms line
then if your machine is unable to service interrupts for each character
then one character overwrites the older one, and in such cases I replace
the even with a binary 7 code as a warning that trash exists. Use flow
control for serial comms lines to help this problem.
