Hi, I need some help to close a connection on a single port that its using Realport, becasue when I use the IP address of the PortServer an the logical port to stablish a connection and I try to close it, it work, but when I´m using the real port to connect by selecting COM1 it doesn allow me to close it. I´m using it to make calls trough an analog modem with a RS232 protocol.
