Publication 1756-RM004B-EN-P - October 2000
Programming the MVI Module 6-3
If a command interpreter is not needed, the user application may be
executed directly from the CONFIG.SYS file as shown below (where
USERAPP.EXE is the user application executable file name):
SHELL=A:\USERAPP.EXE
The user application may also be executed automatically from an
AUTOEXEC.BAT file, or manually from the console command line. In
either of these cases, a command interpreter must be loaded.
The following lines are necessary to provide resources for the OS,
application, and interrupts:
SYSTEMPOOL = 6000
STACKS = 10
Command Interpreter
A command interpreter is needed to boot the 1756-MVI to a command
prompt or to execute an AUTOEXEC.BAT file. Two command
interpreters are included in the DOS directory of the CD ROM: a
full-featured COMMAND.COM, and the smaller, more limited
TINYCMD.COM.
See the General Software Embedded DOS 6-XL Developer’s Guide for
more information.
Sample ROM Disk Image
The sample ROM disk image included with the 1756-MVI module
contains the following files:
• CONFIG.SYS Loads the backplane device driver and the
command interpreter
• TINYCMD.COM Command interpreter
• MVI56BP.EXE Backplane device driver
• SAMPLE.EXE Sample application
• AUTOEXEC.BAT Automatically runs files on startup
• BARCODE.EXE Sample application
• MVI56DD.EXE MVI API device driver
• RY.EXE Y-modem receive utility
