Perhaps the original sender was wondering how to tell if
the BLOCK of data is finished.

If this is the case, you have to design a "protocol". It
might be as simple as "A gap in the transmission lasting at
least one character time denotes the end of the data."
Otherwise, you might want to consider framing characters -
these are unique characters that never occur in the data
and that denote the beginning and end of the block (or
frame).
