"Comm Operator is a powerful tool for RS232 related works. It can act as peripheral devices using COM port, such as GPS receiver, total station, relay boards, etc.for software development. It can also act as a debug tool for device's test and development. The built-in event driven auto send mechanics makes Comm Operator a full functioned device simulator with just a few mouse clicks. By this way, RS232 related software can be developed offsite, no need for device, only the rule script is enough." .....
