Here are the patches for PC DOS 3.2 (Some of them will not work for MS DOS,
if somebody is interested a could get them for MS DOS (I hope))
I found them by looking at the patches for dos 3.1 and some session with
debug.

   AUTOMATIC INSTALLATION OF PRINTER FOR DOS PRINT

   DEBUG PRINT.COM
   -E 190d<cr>
   xxxx:190d   E8.90  D6.90  02.90<cr>
   -E 191F<cr>
   xxxx:191F   CD.90  21.00<cr>
   -W<cr>
   -Q<cr>

   If the printer port is LPT2 then the following address must ALSO be
   modified as follows:

   -E 11c2 4 "LPT2"

   **********************************************************

     PATCH FOR DEAFULT ECHO OFF IN BATCH FILES

   DEBUG COMMAND.COM
   -E 1B2C<cr>
   xxxx:1B2C   01.00<cr>
   -W<cr>
   -Q<cr>

     Note 1: The default for AUTOEXEC.BAT files will still be ECHO OFF.
     Note 2: If the last thing done in a .BAT file is to do ECHO ON, then
             you will get two prompts at exit.

   Patch for echo off in autoexec.bat (dos 3.2) :

   DEBUG COMMAND.COM
   -E 115E<cr>
   xxxx:115E   03.02<cr>
   -W<cr>
   -Q<cr>

   **********************************************************

   BLANK LINES FROM ECHO

   if you apply this patch you can use ECHO with two spaces to echo a blank
   line instead of the ECHO status

   DEBUG COMMAND.COM
   -E 3A88
   xxxx:3A88  E8.83  20.F9  00.02  74.72<cr>
   -W<cr>
   -Q<cr>

   If you want Echo to echo a blank line after only one instead of two spaces 
   use this patch instead :

   DEBUG COMMAND.COM
   -E 3A88
   xxxx:3A88  E8.83  20.F9  00.01  74.72<cr>
   -W<cr>
   -Q<cr>
