There is a detailed explanation on how to install the Keyspan drivers in this thread, above, and it's absolutely working.
If you are having any sort of problems, they are usually caused by:
-incorrect serial cable
-incorrect drivers installation and/or setup
-incorrect use of VsigX
you need to troubleshoot these as we can't possibly do it. We do not support computer configuration and third parties hardware/software.
all the best
