6. With MDL-DataManager versions prior to 4.0, some virus scan applications
caused com port communication problems. Although no current virus scan
applications are known to cause PC/MDL communication problems, it is not
possible to state that these problems could not recur due to ongoing virus scan
update releases.
Windows 95 operating system or higher: One or more of the programs loaded in your
Startup Menu may be conflicting with the serial communications functions of MDL-
DataManager. Remove these programs from your Start Menu. Use the ctrl, alt, and
delete keys simultaneously on your keyboard to display a list of the programs running
in your startup. After closing the various tasks you should now be able to communicate
with the MDL. One by one, replace the programs (that you use) back into your Start
Menu and attempt to communicate with the MDL. When you can again no longer
communicate with the MDL, you will have located the program or programs that
conflict with the MDL communications. Permanently remove the conflicting program(s)
from your Start Menu.
