Sean,
Cheryl now has my Win 7 usb laptop fully set up now re being able to connect to your serial port PCIII, so next time we hook up, let's at least try to connect the two so we can check to see that they commmunicate with each other properly. I don't have any other serial port device to try it out on. Sound OK to you ? I could visit you at home some time and bring the laptop along. No rush, perhaps ideal would be when we get the Amsoil thing all taken care of.
Sandy
