I need installable software that will control physical or virtual COM (RS232) port. Desired behavior and flow: 1. Software shouldn't block COM port, so other program will be able to use it. 2. Once external program sends communication to COM port, this communication should be buffered and exposed to third party software for analyzing. 3. Once analyzing id done, third party will notify COM controller if buffered message should be passed forward thru the port or not Use case example: We have POS software that is connected to receipt printer via COM port. Once receipt is available, POS sends it to predefined physical COM port, where printer should be connected. I want to be able to control what is sent to printer according certain logic. COM controller application should catch communication coming from POS to COM port, expose it to another process (by saving it to predefined folder for instance), and hold it until analyzing is done. Analyzer application will decide if receipt will be printed or not. if analyzer decides that receipt should be printed, it notifies COM controller and controller sends the communication thru the port to printer, otherwise, controller cleans the buffer and ready for next communication. COM controller should be compatible with all versions of Windows from XP and later.

Hello, I can develop a system for your project. 1 - I will develop a software with virtual com port. 2 - This software will act like printer and take print data from pos software. Pos thinks receip printed. 3 - Software sends data for analyze ( or it can analyze itself ). 4 - If analyze result is positive, than software acts like pos and sends print data to printer over physical com port. I dont have previous similiar software, but i have a lot of experience on com port communication. You can see a VR roller coaster simulator on my portfolio ( in freelancer.com profile ) That machine uses serial port communication between software and electronics of mechanics. Requirements : We should listen and record printing process and we should know what necessary for printing process to imitiate same communication. I can guide you to get an image of printing communication.

Software shouldn't block COM port, so other program will be able to use it. Impossible to do 2 software cannot be on the same COM, as far as i know. I am a Delphi RS232 specialist. See www dot limelect dot com efes hamesh efes hamesh arba arba arba arba hamesh sheva. Good luck
