nrComm NET is set of .NET components, classes and routines for serial communication tasks. Library helps to get access to various devices: native and virtual serial (RS232) ports, Human Interface Devices (HID), USB, GPS and others. It provides solution for quick implementation any data packet protocol and contains ready solutions for Modbus, Kermit and ASTM.

VMProtect protects code by executing it on a virtual machine with non-standard architecture that makes it extremely difficult to analyze and crack the software. Besides that, VMProtect generates and verifies serial numbers, limits free upgrades and much more. Serial Numbers. The Ultimate edition of VMProtect allows to add serial numbers to the protected application with minimal efforts. The feature is supported by PayPro Global e-commerce provider, so you even don’t need to setup your own serial number generator (of course, you can do that if you really need). Licensing feature allows to limit the period of free updates, set the time of life of serial number, prevent the code execution without serial numbers and much more. Any serial number can be blocked and newly protected files will not accept it.
