[comp.sys.ibm.pc.programmer] Help wanted to drive an HP7475 plotter

Hi, I'm writing an application that can use an  HP 7475 plotter.
Unfortunately, the reference manual with HP7475 is written
in HP BASIC, which is hard to understand. I'm using MSC 5.1
compiler and the plotter uses RS232 for communication. 
I want to be able to use the plotter to plot histograms with
titles, markers, etc; no sophisticated plotting is involved.
Can someone enlighten me on how to set up the RS232 port
properly to communicate with HP7475, or better yet, point
to some public domain/shareware that uses HP7475 to plot
histograms? Any C or Pascal source will be fine. Thanks
in advance. Please reply to cjchiu@caen.engin.umich.edu
