APPLICATION NOTE #174
 USING IRMA 2/E78 PLUS WITH XYWRITE
 Rev. 01

 IRMA 2/E78 Plus package, a product of Digital Communications 
Associates, is a communications product that allows you to emulate an 
IBM 3270 mainframe with your PC. This application note describes the 
special setups needed to run E78 Plus with XyWrite.


 INSTALLATION
 First be sure that you have enough extra memory to run the emulation 
program. Remember, XyWrite requires 256K of memory (384K with the 
Spelling Checker). You must add to that the amount of memory required 
by the emulation program and any other programs that you have loaded.

 If you have sufficient memory, install the E78 Plus program according 
to the directions in the IRMA 2 Hardware and Software Installation 
Guide. If you decide to modify the AUTOEXEC.BAT file to load E78 Plus 
automatically, enter the E78 command before the command to load 
XyWrite.


 DEVICE DRIVER
 Depending on how you install it, the E78 Plus setup program may 
insert the KYBDDRV.SYS device driver in CONFIG.SYS. If it's there, be 
sure that it includes the G switch as one of the options.

 DEVICE=KYBDDRV.SYS -G

 The G switch ensures that the DOS buffer is where XyWrite expects it 
to be.

 If the device driver KYBDDRV.SYS is not installed in CONFIG.SYS, use 
the /K= switch with the E78 startup command to establish the DOS 
buffer location. Type the following command either in your 
AUTOEXEC.BAT file or at the DOS prompt.

 E78 /K=-G

 (You can use the /K= switch to establish several options. Refer to 
Chapter 4 in the E78 Plus User's Guide for more information.)

 HOT KEYS
 The standard hot keys for entering and exiting the E78 Plus emulation 
program are Shift-Shift.
