1. Initialize the machine- IN;

2. Pen Up command - PU

2. Pen Down command - PD

3. Pen moves to x,y position, absolute from origin - PAx,y

4. Pen moves to x,y position, relative from current position - PRx,y

####  Copy the name for your USB to Serial Device for when you setup the MH871 object

e.g. "/dev/tty.KeySerial1"

in ofx:

string serialPort = "PASTE SERIAL NAME HERE"

plotter.setup(serialPort)

in processing:

String serialPort = "PASTE SERIAL NAME HER";

plotterPort = new Serial(this, serialPort, 19200);

For ofx, download and use Dan Moore's [openFrameworks addon](https://github.com/danzeeeman/ofxMH871). Move it to your addon folder.
