After I tested it, the operation seems like below: Legacy AP <--read-- Port Message Queue <--- send --- "Remote Montoring Tool" In this case, Legacy AP opens COM1 which is a physical hardware port, however, "Remote Montoring Tool" still can send message to COM1. In the meanwhile, if you use another COM port application like Hyperterminal to open COM1 again, error occurred. Becasue COM1 was occupied by Legacy AP. Weird~ Is there existing COM port messages that can be posted to COM queue?
