Hello, I have upgraded to system 9.1. I need a copy of: Momentum SmartPorts 7.0 to switch serial ports with my Q-Port, which is hooked to my Duo Dock Plus with a Duo 2300. The Old Software, version 5.1 that worked with system 8.1 won't work with 9.1. Anyone know where I can get the software? Thank you, Mel Fullmer
