AutoCAD R12 LAN Patch
Some LAN software such as 3COM, DEC Pathworks, and IBM Lan Manager
do not correctly support DOS interrupt 21h, function 6Ch (extended
DOS open) when running MS DOS 4.0 or 5.0.
This self-extracting patch will modify your R12 ACAD.EXE
to work around this problem.
Copy this routine to your AutoCAD executable directory and run it.
It will create a file called ACAD.NEW which you must rename to ACAD.EXE.
(Saving a copy of your original ACAD.EXE is probably a good idea.)
If you choose the option to remove the patch, this utility operates
in a similar manner. It will read the ACAD.EXE file and create a file
named ACAD.NEW.
Temporary ACAD.PWL, and *.ACL files.
The DOS 21h, function 6Ch (extended DOS open) failed on these LAN's
by opening the requested file but returned an incorrect status.
Amoung other things, this created zero length temporary files which
must be erased before running AutoCAD. These include the following:
File Name File Location.
ACAD.PWL This file is in the ACAD.PWD read/write directory.
*.ACL These files may be found in several locations
including your current directory, the directory
that contains your drawings, the directory
pointed to by ACADPAGEDIR, or the temporary file
location specified during configuration.
These files will all be zero bytes in length and should be erased.

You will need approximately 3 megabytes of available disk space.
