A message is defined as a string of characters ending in a user selectable delimiter. Data can be sent to a host module from one port while receiving data from the host on another port which increases the modules versatility. When in the command mode, the module can send messages to a programmable control module where character or string recognition can be performed. The M-Series peripheral communications modules differ only in their communications protocols. The V74 has four EIA-232 ports which use eight pin modular connectors.
Message detect with command or immediate reporting and full duplex.
