Virtual Null Modem. Caractéristiques


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.
