Note that windows will assign a different COMx for each separate usb port on your machine, so if you don't plug the adaptor in the same plug things can get confusing. The one we are interested in is "USB Serial port (COMx)" if x is between 1 and 4 we are fine. click on the plus sign next to the icon, this will open up a list of all your ports. WIN XP: settings->control panel->maintainence ->system->hardwareīOTH: then select device manager this will bring up a display of all your hardware.

To fix this you need to reassign the com port. Windows may assign a higher com port to your USB converter. (For those of you wanting to build a USB version consider that a BIG hint )Īnother trick with the USB converter that you will need to be aware of is that WINALDL only looks at the first 4 com ports. If you already own a serial->usb converter by all means give it a go but if you want to buy one the best ones are based on a FTDI serial converter chip.
