Connecting to the Active Client Monitor Protocol for Real-Time Data Management

DESCRIPTION

This document outlines the process for establishing a connection to Monitor (8180) using the Active Client protocol. It details login procedures, including sending IDENT and PASSWORD commands, and retrieving host port for communication. Steps for maintaining the connection, including "Are You Alive" transactions, are specified to ensure the server remains responsive to client commands. The protocol is critical for real-time data management and monitoring, designed for efficient client-server interactions and maintaining connection integrity.
