We have the version 5 of SEC but we are prompted that we need to get a newer version if we will buy a new license. So we tried to setup our previous configurations to the newer version and it doesn't work. We used Virtual Serial Port Driver build 7 to establish serial port pairing. After establishing it, we use SEC to make the two serial ports available over the internet.
The problem is that in the newer version of SEC we can't establish a "real port" from the Virtual Serial Port Driver (VSPD), instead a "virtual port" is being implemented. We can't disable the "Create as virtual serial port" checkbox although we established the communication ports from the VSPD.
