HPGL Syntax

I can find examples of code for HPGL and I have been able to get the
plotter to do a few things using my BS2. But I still need to find a
FREE list that can tell me the Syntax of the commands and maybe a bit
more on what each one does. I don't want to go and BUY a book on
HPGL. I only need to know simple commands.

For example: I can use the LB command to make the plotter write text
but I don't know how to take it out of LB mode. It will just keep on
plotting out the other commands after the LB command, thinking that
it is all text that I want it to plot.

If there are any solutions other than buying books, let me know.

thanks.

I wish to interface my BS2 with my HP 7475A Plotter. I have
connected my BS2's pin 0 to the serial in line of the plotter. I am
trying to send Text to the plotter at 9600 Baud, No parity, 8 Stop
bits. So far, All I can do is get the Error light on the plotter to
flash. heh. So I gurss it is recieving the data. I just don't know
how to program the Plotter to plot simple strings of text. Can
anybody help me out with programming this thing? Thanks.

    I posted four PDF files at
    <http://www.egroups.com/files/basicstamps/> which are scans of the HP
    7475A Plotter Reference Card. Hope this helps.
