README.TXT: for the VDF Plotter ADI Driver for WINDOWS, V 1.02
----------  @ Copyright Océ, 94

This is V 1.02 of the ADI Windows VDF plotter driver for AutoCAD R12
for the Oce G1800, G9800, G1900, G9000 and 9500 (and 1600) output devices.

This driver cannot be used with AutoCAD R11 Windows.


For a brief explanation of usage, run the help file PVDF_DOC.HLP.

Pen width definition:
--------------------
You should pay a specific attention to the way the pen widths are handled by
this driver.
All lines are considered as if they were all plotted with a physical pen of
width 0.2 mm. This implies that: 
 
 + line thickening is considered active when the pen width defined in AutoCAD
   is greater than 0.2 mm.

 + ON PEN PLOTTERS:
    A line defined with a pen width in AutoCAD smaller than 0.2 mm will be 
    plotted with a single vector. The line generated will therefore be of the
    width of the physical pen used.

    A line defined with a pen width in AutoCAD greater than 0.2 mm will be 
    plotted as a thick line with parallel overlapping vectors. A physical pen
    of width 0.2 mm is mandatory for a correct solid fill. 

    If you don't want to use line thickening, leave all pen widths in AutoCAD
    to their default value of 0.005 inch. All lines will be plotted with the
    exact width of the physical pen present on the carousel.       



 + ON RASTER PLOTTERS:
    A line defined with a pen width in AutoCAD smaller than 0.2 mm will be 
    drawn on the plotter with the width which has been set for the
    corresponding pen on the machine's front panel.

    A line defined with a pen width in AutoCAD greater than 0.2 mm will be 
    drawn as a thick line with parallel overlapping vectors. The driver
    assumes that the pen defined on the machine's front panel is thick enough 
    to generate solid fill. Since the overlapping is of approximately 30%
    of the assumed vector width, setting the actual width at the front panel
    to 0.16 mm (or close) is correct.

    We suggest that:
      - for the pens you want to be plotted with a width inferior to 0.2 mm,
        set the corresponding pen widths at the machine front panel to 
        the minimum width possible.
      - for the pens you want to be plotted with a width superior to 0.2 mm,
        set the corresponding pen width at the machine front panel to 0.16 mm
        (or close).

Serial communication:
--------------------
The driver uses XON/XOFF protocol in communication with the plotters over
a serial line.  This is a change from the CTS/RTS protocol used in previous
AutoCAD drivers.
On the plotter panel, choose XON4 or XON/XOFF as the protocol.  This is a change
from the factory settings on some models. Note, however, that when using
Autospool from DOS, the plotter must be set for CTS2 (HARDWARE on some models). 
See the file AUTOSPOL.DOC for more information on Autospool with PLPVDF.


New with AutoCAD 12 Windows:
---------------------------
Certain Oce-specific plotter parameters are now set from a dialog box rather
than a text screen.  To access these parameters, select "Device and Default
Selection" from the Plot dialog box, then select "Show Device Requirements" to
see the current settings, and/or select "Change Device Requirements" to change
the settings.

The Oce-specific parameters are:

	Copy Count
	End-of-Plot action (Move Clear, Move Page, or no action)
	Plotter Port Timeout (in seconds)

If the AutoCAD variable CMDDIA is set to 0, all plot dialogue will appear on a
text screen, as in previous releases of AutoCAD.

If the plotter is said Offline by AutoCAD in the middle of a complex plot, try to
resend the plot with a larger time-out value (0 seconds for an infinite time-out).


Pen settings:
------------
You may need to adjust the pen settings at the plotter front panel, so that they 
don't interfear with the ones defined with the driver. For example, on a G9865 machine,
the pen patterns are set at the front panel and cannot be activated or disactivated
from within AutoCAD by the driver.

When plotting drawings with surrounding frames, you may need to plot with a small
offset of the origin (for example x=0.05,y=0.05 inch) so that the left and bottom 
sides of the frame are not partially clipped. The value of the offset will vary with
the pen width used.
