I am in the process creating the PBX communication program that using
2 communication components, the component are using 1 port (COM2), they are MSCOMM and the other one is tailor made DLL, the MSCOMM will receive all data from port and the other one will send the command to the PBX, now I have a problem the MSCOMM is seems like did not close the port completely eventhough I have closed it by using MSCOMM1.PortOpen = false, this problem will causes the other components can not communicate with the PBX, any body can help me?

Best Regards
Winan
