PATCH NAME:
 
                                 PCS3270.COM
 
 
ENVIRONMENT:
 
	This patch is needed for any Compaq VGA machine when running the
	IBM Personal Communications 3270 package, version 1.01, level 0.
 
 
FUNCTIONAL DESCRIPTION:
 
	The PCS/3270 package causes Compaq VGA machines to blank the
	video monitor and lose keyboard response.  This occurs when the 
	user hotkeys from a compressed video mode, such as model 3 
	(32x80), host session to DOS.
 
	This patch compensates for an errant video Set Mode call, in the
	executable files PCSPDOS.EXE and PCSDOS.EXE, which causes this
	anomaly.
 
 
INSTALLATION DESCRIPTION:
 
	1) Load the patch PCS3270.COM into a directory which is defined in
	   the path declaration, preferably in the same directory as the
	   PCS?DOS.EXE files.  If the PCS/3270 application is used regularly,
	   this patch should be included in the AUTOEXEC.BAT file.
 
	2) Enter "PCS3270" to load and execute this patch.  An installation
	   message will be displayed on the video monitor.
 
 
COMMENTS:
 
	1) PCS3270.COM will remain memory resident until the system
	   is rebooted.
