I have a Dynex brand USB to Serial adapter that I purchased at Best Buy this afternoon. It did not work with the USB cable plugged directly before either. I read some get it to work with direct USB, I can't get it to work at all. What settings are wrong? Can someone give me a link to the correct driver and tell me exactly how to install it, maybe that is the problem. Pretend I am stupid, cause I must be missing something minor here.

I have tried everything I have found on this board and can't get the cutter to do anything! Mac OSX 10.5, Serial cable, Signcut software. Please help me figure this out!

I can't get the cutter to do anything. I bought the USB to Serial adaptor, still doesn't work. HELP!

No error messages. I tried installing the Keyspan driver thing, no luck. Cutter doesn't do anything, signcut acts like it is working but the cutter doesn't flinch.

Okay, I have been searching for hours trying to find out why my cutter will not cut. Installed a million things, changed every setting, doesn't make a peep when I try to cut. Signcut is what I am trying to use. I have 10.5.8 Hooked up with USB connection. What do I have to do to install this so I can cut?
