/*
Note the line pair first seen as:
mySerial.print("?"); // first half of the custom character command
mySerial.print(Remainder, DEC); // prints the custom character equal to remainder

This is a clever technique to use the variable "Remainder" to print a custom character
that depends on the (integer) value of "Remainder" using the ?# command where # is expected to be
an integer constant in the range #=0 to #=7.

Sorry for all the posts, the forum wouldn't let me put it one post.
