We haven't tested it yet, but can't think of any reason why it shouldn't. You may need to run it in Administrator mode.
will using a USB to serial cable work on teh H7600
Again, no reason why it shouldn't – the H7600 is expecting RS232 – doesn't care where it comes from. There is a remote possibility that Vsig will not recognize the cable – the solution would be to try a different one.
To conclude – both of these should work – if they don't, we'll have to fix them.
I'm running Vsig 2 on Windows 7 (er, 6.1 <wink>) x64 without problems. I set it to run at XP SP3.
I'm using a USB-RS232 adapter with the Prolific 2303 chip in it. Once I found a recent driver package (from SerialGear.com, IIRC), it came right up. Whatever adapter you end up with, just make sure to set the comm spec in Device Manager as well as in Vsig.
