DVSETPRT
Desqview MX 80 printer setup utility

Dvsetprt.com is a simple program designed to send some of the
common MX 80 control code sequences. I wrote is specifically
to give me a chance to work with the BIOS printer services as
well as try out a few more Desqview routines. It requires a
minimum amount memory to run. In fact it is replacing an
almost identical PD utility that required twice the space. I
only included the some common used control codes since I had
no intention of writing something more extensive at this time.
I hope you can find a use for it from time to time. I have
included NO instructions simply because I believe none is
really needed. Simply install it using the .DVP included in
the archive and you are all set to go. If the printer is not
ready Desqview will 'pop-up' an error window. Correct the
problem then press ESCAPE to clear the error message. The
program currently can not detect when other programs are
using the printer. The program will stop in its tracks until
the contention is resolved. Currently, LPT1 is the ony port
supported.

You are granted permission to distribute this program with the
stipulation that NO remittance is accepted for either the program
or handling and distribution charges. This program may not be
distributed with other programs on disk if a charge is incurred
for any program or for the medium. In other words, if there is
a charge involved then you do not have permission to include this
program, period!


The author makes no warranties expressed or implied as to the quality or
performance of this program. The author will not be held liable for any
direct, indirect, incidental or consequential damages resulting from
the use of this program. Your use of this program constitutes your
agreement to this disclaimer and your releasing the author from any form
of liability or litigation.




Desqview routines used:

1: Checks for the presence of Desqview and exits with an error
if Desqview is not found.

2: The program writes directly to the screen buffer provided by
Desqview.

3: The program releases the rest of the time slice when ever it
finishes sending codes to the printer as well as when there
are no keystrokes waiting to be processed.

4: Desqview interface for generating tones.

5: Desqview interface for displaying the error message. This
used when an error occurs with the printer.

Requirements:

Desqview 2.0 :You MUST have this version or later

Dvsetprt.com :the executable program

Sp-pif.dvp :the program information file used by desqview
(see next section)

Reasonable compatability with the 'standard' IBM is assumed when
running this program. I use interupt 16h to check for key
strokes pending and to retrieve the same. INT 17h is used for
printer handling.



Program information file:

I have provided the 2 screens from 'Change A Program' to illustrate
the required settings should the Sp-pif.dvp be missing or incorrect.
Five points should be noted:

1: Memory size is set to 2k. More is not needed, less will
produce an error message.

2: Maximum and starting screen size is set to 19 for the height
and 30 for the width. Increasing values will distort the
display. Decreasing these values can cause serious problems
when the program tries to write to memory that is not
allocated to it.

3: All memory options on the Advanced screen are set to zero.
changing this will only allocate memory to the program
that will not be used and is therefore wasted.

4: The close on exit to DOS option is set to yes. This
allows Desqview to use its own shell.com instead of
command.com to load the program. The saves a nice
chunk of memory that would otherwise be wasted.

5: The program will appear on the Add a program (other)
menu as Desqview Set Print. Keep this in mind in case
you have a problem finding it.

Compatability:

This program has been successfully run on the following
three machines:

1: Compaq 386 (CGA emulation)

2: IBM 8mhz AT (monochrome graphics)

3: My 8mhz XT. (color) This machine is an example
of the extreme in that the parts were purchased
from at least 7 different manufactures, none of
which are known for their large market share.
The CPU is a NEC V20 and the BIOS is by PHEONIX
(version 2.26)

The End:

I have written this program because I have not found a
satisfactory alternative. I have learned a little about
assembler along the way and consider that sufficient
compensation for the time and effort spent on this
program. I do have an EGO so feel free to send comments
using one of the methods provided above. Users that are
in the same stages of learning assembler as myself may
have a copy of the source as an example of actual uses
for the routines Quarterdeck provides. Experienced
assembler programmer's will be bored and only point out
all the different areas where my ignorance of assembler
shines through.
