I've got it working, just about, through a USB==>Serial adapter. The problem is identifying the command set. Every reference I can find assumes you are using the Fortran HCBS file set, which I cannot locate. I've got all the manuals, and I've identified most of the basic commands I need, there's just a couple I'm lacking. If anyone knows what they are I would be very grateful.
I've included all those I know below, for anyone who runs across this after obtaining their own plotter.
Known useful commands:-
%X/%Yk Moves to absolute point X-Y
%X/%Yj Moves to relative point X-Y
i Lower Pen
h Raise Pen
o%Rk Draws a circle (or arc) of radius R
F%P Selects pen P
Known, less useful commands:-
b%abc Plots all following ascii chars is text (cant stop it currently)
v Draws a box, cant control it currently
x%X,%S,%H Plots an X axis, with markings at S intervals of H hight.
y Same as X axis
l%C Dashes, 0 turns off.
Missing, useful commands:-
Sleep/delay (currently races off after pen up before the pen get's up!)
Speed control
stop text (see b)
font settings etc
Any help with this last few would be very welcome.
