Hello,

I am attempting to upgrade the software on our Harman Kardon AVR354 by using a RS232 USB to serial port adapter and it is asking what port I am using. The computer is an older Dell Dimension 4600 with 2 front USB ports. I can't find any documentation on the Dell web site that will answer which setting Com 1 or Com 3 or some other setting should be used. Does anyone know the Com settings for those front USB ports on my Dell or where I can find the information?

Thanks

A usb port can be any number of 'com port' numbers. com1 and 2 are normaly reserved for serial ports.

if you unplug the the adapter cable from the computer, then go into device manager and look under the com ports. look at what is there. then, whilst device manager is open, plug in your adapter cable.
it will install and add a com port to your device manager. this will be your com port number that you are after.
