CPU speed: Recommended 1 GHz or faster – our software may run successful on certain slower CPUs but because of Windows overhead, performance test results will not be as accurate.


Memory: Recommended 256 MB.


Free disk space: Virtual Null Modem takes up about 5 MB but additional space required for log files.


Special login requirements: You must be logged on as a user with Administrator privileges to run our software. It is necessary for access certain registry keys and plug/eject/install virtual serial ports.


Microsoft Vista notes:


Because our software uses a kernel-mode driver for creating virtual serial ports, therefore:


1.You need administrator privileges to run our software;

2.The desktop icon of our software will contain a shield (fig. 1);

3.Windows Vista will ask your permission to continue (fig. 2).
