HP 80 SENDING DATA
Plotter-to-Computer
Transmitting data from the plotter to the computer is typically accom­
plished using I/O statements such as READ, INPUT, and ENTER.
Sometimes these statements are only available in I/O ROMS; check
your computer's documentation or ask your HP dealer or HP Sales and
Support Office. The following examples of obtaining output data from
the plotter using various computers are only intended to illustrate the
necessity for understanding the I/O statement protocol implemented
on your computer. Each of these examples commands the pen to move
to plotter coordinates 1000,1000and then output the current pen position
and the plotter identifier string to the computer.
