Zlvircom installation instructions:

If you don't need virtual serial port function, just need device management and configuration, please run zlvicom.exe directly. If you need the virtual serial port function, install virtual serial port-control.msi(download from:https://www.fabulatech.com/dists/vspc/virtual-serial-port-control-64bit.msi) to the default directory first, and then run zlvircom.exe .
