And, try to make sure the USB-to-Serial adapter isn't using a counterfeit FTDI chipset!

I buy my FTDI based USB-to-RS232 cable sets from Elecraft with no issues.

Comports and serial port are the same thing. Most newer computers don't have serial ports or comports. Instead they have USB ports. When you purchase a USB to serial converter, it makes a serial port out of a USB port. The serial port is then accessed with a comport number just like a native serial port. So, yes, get a USB to serial converter and install it. Make sure the converter uses the FTDI chipset. These converter work much better than the prolific chipset.

Hi, I've never used a USB to serial converter but want to try one now. For the Wisconsin QSO Party last Sunday, OM K9OT wanted to use his Orion with the N3FJP contesting program and a small Thinkpad X40 laptop running XP SP3. His CW interface has a serial connection for the laptop and has worked in the past. However the latest 3.5 version of the N3FJP WQP program only supports com ports, not serial, so he had to use an older version 2.0 of the program that I downloaded. That worked okay in a pinch but he would like to try the new version.

The Ten-Tec website carries a USB - Serial Converter Cable but says it doesn't work with the Eagle, which we also have in the shack. Out of curiosity, is this because the Eagle has a USB type B port rather than a type A? Would an A to B adapter work? I am trying to think ahead here.

We are NOT looking for suggestions to use a different contesting program since we already know of some. I just want to know if the TT converter can be made to also work with the Eagle, or not. For $32 plus shipping, compared to much cheaper FTDI ones also available online, it would be nice if it can do more than one trick.

For the record, we both use a computer for contest logging but not for control of the radio besides CW. I computer log all contacts in DX4WIN and Paul does paper logging outside of contests. Those get entered in DX4WIN later for LOTW upload.

I hope this all makes sense and isn't too long-winded.
