Started with a laptop on XP and the serial port on my Profilux Plus II, this all worked well.
I put in your USB port on the Profilux, tried to connect with PC Windows 7 and got problems.
So now I removed the USB port, went back to my portable PC / Windows XP and now I cant connect any more.
I am getting very **********.
If I reset my Profilux, I will loose all settings with no guarantee that I can connect using the RS232.

What do you suggest / recommend ?
