Dear User of LPTx,
Here are all of the latest versions of LPTx. The different
versions are not replacements of each other but are different ways of
doing the job. The latest is version 7.00. This version works best
under all versions of DOS and includes a pop-up window for turning
LPTx on and off from within an application program.
This program attempts to do things which are strictly illegal in
DOS. DOS is not re-entrant and with LPTx I try to make it so. Though I have
tried to make this a solid and safe program, I cannot be responsible for
its use. Use this program at your own risk.

User-Supported Software
-----------------------
This program and documentation are copyrighted by Mark C.
DiVecchio.
Permission to copy:
Individuals, clubs and other non-profit organizations are
granted permission by the author to freely copy this program and
documentation and share it with their members, so long as:
- No price is charged for the software or documentation.
However, a distribution cost may be charged for the cost of
the diskette, so long as it is not more than $9 total.
- Club members are informed of the user-supported concept and
encouraged to support it with their copyright fees.
- The program and documentation are not modified in any way
and are always distributed together.
Schools, universities, and other non-profit organizations are
granted permission by the author to copy LPTx for use on other
computers and at other locations in the organization, so long as:
- The full fee of $25 has been paid for the original copy of
the program.
- A usage fee of $40 is paid for each additional building
where LPTx will be used. Within each building for which
the usage fee has been paid, LPTx may be copied freely for
use on any other computer in that building. Contact the
author if you would like to make other arrangements.
Commercial users of this program are required to submit the
copyright fee. Commercial and site licenses as well as source
code licenses are available. The site license is handled as a
graduated per copy fee. Contact the author.
The User-Supported concept:
User-Supported Software
If you are using this program and find it to be of value, your
copyright fee will be appreciated. ($25 is suggested)

Regardless of whether you pay the copyright fee, you are
encouraged to use, copy and share this program.
User-supported software is an experiment in distributing
computer programs, based on these beliefs:
- That the value and utility of software is best assessed by
the user on his/her own system.
- That the creation of personal computer software can and
should be supported by the computing community.
- That copying of programs should be encouraged, rather than
restricted.
Anyone may request a copy of a user-supported program by
sending a blank double sided double density, 360Kb formatted disk
(without DOS) to the author of the program. An addressed,
postage-paid return mailer must accompany the disk (no
exceptions, please). A copy of the program, with documentation
on the disk, will be sent by return mail. The program will carry
a notice suggesting the payment of a copyright fee to the
program's author. Paying that copyright fee is completely
voluntary on the part of each non-commercial user. You can also
call my RBBS at 619-549-3927 for the latest news.
Free distribution of software and voluntary payment for its use
eliminates costs for advertising and copy protection schemes.
Users obtain quality software at reduced cost. They can try it
out before buying, and do so at their own pace and in the comfort
of their own home or office. The best programs will survive,
based purely on their quality and usefulness.
Please join the experiment.
If you believe in these ideals, the copyright fee is solicited
to help make them work.

Programs on this disk are:
--------------------------
LPTX301 Fixed a small bug which sometimes causes LPTx
to hang when first loaded.
LPTX401 Corrects the same bug as LPTX301
LPTX500 Version which uses DOS critical section flag and
takes over both interrupt 17h and 21h.
Works better under DOS 3.x but does not capture
as much output as LPTX300.
LPTX600 Version which uses a combination of the DOS critical
section flag and the timer interrupt 08h to empty
memory buffers. I've tested it under DOS 3.1 with
the software that I have. Look at the associated
DOC file for the programs that cause trouble.
LPTX700 Version based on the functionality of V6.00 but
includes a pop-up window for turning LPTx on and
off. This version was written by Kepa Zubeldia who
has permitted me to include it in my distribution.
The .ASM has his address if need to get in touch
with him.
LPTX70A Just like version 7.0 but with a single 40K buffer
supporting LPT1 only. This might help in some cases
where LPTx does not get enough cycles to empty the
original 4K buffer.
CAPX100 This is a special utility which I wrote for the express
purpose of capturing the screen to a disk file. The
program itself is called CAPTUR.
Also on the disk are print capture programs written by others
from which I have gleaned (kind of like borrowed) to write LPTx.
FSPOOL.ARC Gave me the idea of saving the DOS stack
REDIRECT.ARC An article written by Dwight K. Illk about LPTx, PR2FL
and LPT2DSK. This article can be reprinted in your local
computer club newsletter per Dwight's release.
Many of these are in ZIPPED library format. I have included the
PKUNZIP program to let you remove the individual program from each library
file. For example, to unzip a version 7, type 'PKUNZIP LPTX700'.
I appreciate the response that I have received from a couple of
letters in the Data Based Advisor magazine and from Steve Ciarcia's plug in
BYTE. From that, I can see that there is a tremendous need for a printer
redirection program for users of programs written in dBase and do not give
a print to disk option.
If anyone figures out how to make a more reliable capture
program which is less dependent on the idiosyncrasies of DOS, please
send me a copy and I will incorporate those ideas into LPTx. Watch the
Athena Systems BBS at 619-549-3927 for future updates.
Good Luck,
Mark
------------------------------------------------------------
I have also authored a VT100 Terminal Emulator called PC-VT. It is a
complete communication package that specializes in VT emulation. You can
get a copy from many of the PC Library companies, from RBBSs (The best
bet is, of course, mine at 619-549-3927), or directly from me. Send a
formatted 360K diskette and a self-addressed postage-paid mailer to me
at the above address.
