TSP TEXT STARTING POSITION
This parameter marks the starting position of the character in the text string to be used as
data. This is useful for allowing several fields to use sections of the same text string,
minimizing the amount of data transmitted. For example, for the text string 0123456789, A
TSP of 5 and a CC (character count) of 2 would print 45. See section 5.3.4 for use of this
parameter with clock fields.
