This is a tiny Python script that can plot a HPGL file over a simple RS232 serial port (by doing manual handshaking with the plotter). Manual handshaking makes it possible to use a three-wire serial cable (RX, TX, GND) and/or a cheap USB-to-RS232 adapter to communicate with the plotter.

It currently supports the HP 7475A (or compatible) plotter.
