From: David Esler <drumandst...@gmail.com>
In 9180f5365524 a change was made to the send_chr function to take in
C-strings and print out a character at a time until a NULL was
encountered. However there is no code to increment the current character
position resulting in an endless loop of the first character. This adds
a simple increment.
