NPS-API Webservice

High volume number plate testing against the NP Tracker suspect and suspicious vehicle database.

Webservice

Webservice is a computer communications protocol, providing full-duplex communication channels over a single TCP connection.
The Webservice protocol enables interaction between a client-side application and a web server with lower overheads, facilitating real-time data transfer from and to the server. This is made possible by providing a standardized way for the server to send content to the client without being first requested by the client, and allowing messages to be passed back and forth while keeping the connection open. In this way, a two-way ongoing conversation can take place between the client and the server. The communications are done over TCP port number 40.

Commands

Usage: ping
