ComSpy2 is the second generation of a tool developed in 1997. It was originally developed to listen on serial COM ports and then expanded with LPT, USB Printer interface, File I/O, TCP/IP and UDP. The data can be presented as ASCII, HEX, ANSI Terminal, Graph or capture bitmap streams.This new edition is redefining the concept from a strict communication path to a true object oriented way of handling smaller data flows. This is not an analyzing tool for major data flows or low level communication protocols. It is designed for smaller data packets such as sending commands and processing answers to/from external devices.A script object makes it possible to analyze incoming data and to create scripted UIs with Buttons, Edit fields.The scripted UI can fire test cases, for example automate FW tests on external peripherals connected to any supported communication object.Each type of object can have inputs and/or outputs, known as channels. The data flow is routed through the objects for processing.The data flow is designed by easy drag & drop of objects from the object panel and then routed by dragging the outputs to the inputs.The software becomes more useful if you are a hardware or firmware developer. The intention of the program is to communicate with your hardware before you have any software supporting it. With the scripted GUI you can send down sequences of test data. With the View objects you can present data from your communication port. The program can of course be used in other areas, for example; create a SMTP client, MUD client, Syslog server.
