Inter-computer communication method and apparatus utilizing clocked message playback and message format definition files

摘要

An inter-computer communication method and apparatus permits inter-computer communication of computer messages having a format easily defined by user in an ASCII configuration file. Instead of rewriting code to accommodate a differently formatted message, the invention utilizes an ASCII configuration file that can be easily created and changed to define various message formats. Message encodation involves inserting a unique header in the message identifying the message format and building a message according to the defined format. Message decodation parses this header to access the configuration file and determine message format. A message processing apparatus processes inter-computer messages in one of three configurations including a first configuration for processing input messages from a communications port by controlling a message decoder to decode input messages and send the decoded input messages to a processor for manipulation by an application program; a second configuration for playing back an input message from the message log and sending the read input message to the processor for manipulation by the application program; and a third configuration for logging inputs by routing input messages from the communications port to the message log.
