Introduction
Virtual Null Modem has two cut down versions
called Virtual Null Modem Lite and Virtual Null Modem Standard. These versions omit some of the advanced features
found in the Professional edition. They are ideal for users who
either want a low-cost solution or are not interested in more
advanced features.
This page lists the principal features of Virtual Null Modem and identifies those features that are not available
in Virtual Null Modem Lite and Virtual Null Modem Standard.
Virtual Null Modem Lite sells for 40% of the cost
of the Professional version. Users can upgrade to the standard
or professional version at any time, only by paying the
difference in price between the versions. The actual software
is identical since the software protection key is used
to configure the Lite or the Standard version. A code can
be sent by email that allows the user to upgrade the software.
