Everything works great!
I kept this thing because I tried a different PCI Serial card and Vista would not recognize it, couldn't find a driver to make it work but this one does! Oh, and Newegg is awesome!
Works great! I currently use DOSBox to run some old engraving machines on Vista Home Premium; I was able to set the port and ditch the old 286 it used to run on
It fits into the normal PCI slot but only comes with the extremely small metal plate to cover the back of the computer; Still haven't figured out what I'm going to do to securely close it, just have it carefully pluged in and hope it doesn't wobble loose while engraving
