<p><b>Notes:</b>
All characters are displayed, including CR, LF, and BS.
Replication count in CX may produce an unpredictable result in graphics
modes if it is greater than the number of positions remaining in the
current row.
With PhysTechSoft's PTS ROM-DOS the BH and CX values are ignored
on entry.
