My read of the question was to convert the byte value to packed BCD to send
to consul.  how the consul would display them would depend on the  consul I
guess.  That is why I mentioned the term BCD, as using that term would have
avoid confusion.  But he could want a ASCII representation of the decimal
value of the byte.

If he wants to see if the byte is a printable character or a control
character (or other nonprintable character), I would recommend he convert
the byte to two hex ASCII characters.  May be easier to look up on ASCII
code charts.
