I first read about Portmon today as a diagnostic for a HRD problem.
A search in this forum gets no hits for "portmon".

Reasons for my posting today:

1. I'd like to know if Portmon can be used to diagnose "USB-to-RS232" converter problems.
Even though I have the latest, up-to-datest Keyspan-drivers, I do have an on-going issue with Keyspan USA-19HS working with Vista.
The Keyspan device works fine with XP.

2. In googling on "portmon", I see there is some concern about it having a virus; is there some site from which Portmon can be downloaded un-infected?

I have a Yaesu FT-950 with HRD 5. I just purchased a new Windows 7-64bit laptop, and when searching for a USB-serial adapter, I found many companies that do not support Vista or yet. KEYSPAN IS ONE OF THEM. JUNK! I even emailed them, and they didn't have a answer as to when they would release a driver. Hello! Are they serious?

Anyway, a search followed, and I purchased this apapter:

http://www.usbgear.com/computer_cable_details.cfm?sku=USBG-232&cats=106&catid=482%2C1303%2C199%2C461%2C106%2C1009%2C601

It supported all modes of Vista and 7. Works like a charm and I have never looked back. I would dump the Keyspan, if I were you.

I have the USBgear converter and driver. It doesn't work for me.
I noticed that they say it works for "MOST" applications (not all.)

In the future I won't buy any transceiver or ham equip. that doesn't
have a USB port or whatever the new laptops will be using.

That is good advice from N4NYY.
After spending hours and hours trying to get the Keyspan USA-19HS Angry to work with my Dell-Inspiron-1525-laptop, I gave up on it.
I bought Radio-Shack's Gigaware device and it works just fine Smiley.
The local Radio-Shack had it in stock and I got $10 off due to a coupon from a previous purchase.

The problem is that it won't guarantee that you won't still have issues at some point. Even though the USB is built into the radio, it still requires a driver on the computer. Upgrade the operating system and the radio's USB may not work until you get a driver for the new operating system. If the radio mfg choose to use usb chips that don't have good long-term support then you may find that you have a boat anchor. Printers are a good example. Many otherwise working printers ended up in the scrap heap because the mfg never provided driver support for a new operating system? At least USB to RS232 converters are relatively inexpensive.

For those older DB-9 style boatanchors, see FTDI's DB9-USB-RS232 Modules.
$22 each from Mouser.  Does need the free FTDI driver (Windows 7, Mac, or Linux).

http://www.ftdichip.com/Products/EvaluationKits/DB9-USB.htm

"DB9-USB-RS232 range of modules provide a simple and fast method of migrating existing DB9 based RS232 connector interfaces to USB 2.0, without the need for any board re-design. The modules feature a USB2.0 mini-B connector on a module which fits a standard 9-pin DB9 connector footprint. "

"Ideal for legacy applications which feature DB9 based RS232 connectors.  The modules provide a method of extending the life-cycle of these products with USB2.0 connectivity, with minimal redesign."
