The virtual COM port seems like a really innovative and cool idea. It eliminates the need for multiple ports since it can create virtual ones through a number of different ways. The only thing I think would be a problem is since they can be created via TCP/IP, that makes a persons computer susceptible too hacking. I think, I am no tech expert, that gives access to the hard drive and other essential files of a computer. Beyond that I think it is a great idea.
Nodegrid Services Router is a modular open platform appliance designed for software-defined networking (SDN), out of band (OOB) management, DevOps, SD-WAN, remote/branch offices, retail locations, and network function virtualization (NFV) capabilities. Nodegrid Services Router is optimized to perform various network functions including switching, routing, security, WAN acceleration, provide secure OOB remote access, run Docker and Kubernetes applications and control IT devices at the edge of the network, and within converged infrastructure (CI) environments.
