Abstract:
A method for providing a connection between a master device having a first protocol and an I/O device having a second protocol and an output, the method comprising the steps of:receiving over a transmission path a request message on a preregistered TCP port selected from a plurality of TCP ports;receiving the output from the I/O device;transmitting a response message from the I/O device over the transmission path in response to the request message, the response message correlating to the output of the I/O device; andlimiting the request message and the response message to a length that is less than both a TCP transaction length and a maximum transmission unit limit and wherein an adapter operably connected between the master device and the I/O device converts the request and response messages to and from the protocols of the respective master and I/O devices.
