Are you sure you are talking on thd correct COM port? The computer is old enough that you should have a physical serial port. That should be COM1 in the device manager.Best Ain’t no family like the one I got T-Shirt Check the device manager to ensure you are seeing at least one COM port and make note of the number and check the laser software for a setting to make sure that’s trying to talk to the correct port.If you are not tech savvy, or don’t have plenty of time to dedicate to this machine skip my comment.

You would be suprised how much it will sell for.

I have no idea, I installed windows XP service pack 3 and the software with machine driver that came with the machine. I also went onto dells driver page and downloaded every available driver for this pc. I have a db25 to db25 cable (the machine has a db25 port) I also tried a db25 to USB converter but still get the same errorBut it’ll free up ALL of them. You may need install serial drivers again.
