Opps!
Problem not to do with this thread!
Was due to the 2nd table not being set up correctly. Didn't see this one comming as I am not using the 2nd table.....
So now I can say that my PCMCIA Serial card has 100% functionality!

I'm also using the Belkin PDA Adapter. Works fine. The only issues I've had on XP SP2 is that the MS has to be off and the cable needs to be connected to the computer. Once MegaTune is opened, turn on the ignition so the MS is powered up. MegaTune won't show that it is connected. Leave the MS on and USB wired to the computer, close MegaTune, and open it again. It connects about everytime. If I do it any other way, the computer freezes and needs restarted.

Rick,
The controller's ini (megasquirt-I.ini or msns-extra.ini)...

They seem to be as solid as a built-in serial port by all reports,
it's only certain combinations of USB adaptors and machines/OS
levels that seem to work strangely with the windows comm API.

I finally got some USB adaptors to see what I could find out. I've received three of them, and have tested them on two laptops and two MSs with different processors/firmware/baud rates, here are the results.
TrippLite U209-000-R $18.48
Hawking Technology HUC232S $18.99 (Windows reports this as a Prolific)
Belkin F5U109 $24.59
MicroInnovations - hasn't arrived yet...
All adaptors were installed using their delivered drivers with default settings (no fifo buffers were changed or comm ports re-assigned after installation). The two test machines were my old Dell Inspiron 7000 running aftermarket W2k pro and my wife's Dell Inspiron 2650 running the Dell-installed XP. Results were identical on both machines. (XP complained about the TrippLite drivers not being XP certified during installation.)
I tested both MS-I v3.0 at 9600 baud and MS-II current beta at 115k baud.
Success
Two settings were varied in the respective ini files: writeBlocks and interWriteDelay. All combinations work just fine with writeBlocks=off and interWriteDelay=1. This also works ok with standard comm ports, but may be slower than other settings (who cares, if it works?).
Failures
I could get the TrippLite and Hawking to fail severely (loss of connection requiring reboot of MS) by setting writeBlocks=on. The Belkin would have occasional dropouts, but would recover fairly rapidly, and it seemed from this 10-minute test to be the most robust of the three.
Conclusions
Set:
writeBlocks = off
interWriteDelay = 1
All brands appear to work just fine with these settings.

Update: USPS dropped off the MicroInnovations adaptor about 5 minutes after I posted the above... Physically it is identical to the Hawking/Prolific (other than color and label), and a look at the drivers on the CDROM reveals that they are the same name, size and date stamp as the Hawking. Even their price was identical at $18.99...

Eric,
That's good news, and very useful for people with newer laptops/notebooks (newer meaning newer than my 10 year old piece of crap!).
If you get a chance, and have the time, you might try burning new code with the USB adapters to see if they work.
My adapter, an IOGEAR GUC232A, works fine for everything but burning new code (which isn't essential for me as I have both a programmer and a computer with a standard serial port, but some people might need this function with an adapter).

Lance,
Thanks for the suggestion, that's an important test I hadn't thought about.
I used download with the MicroInnovations/Prolific to burn -E 021x1 (had it laying around) to the MS-I box twice, zoom, no problems. Switched cables and used gms2dl to burn Al's latest MS-II code to my MS-II test box, again, it went very fast for two tries and I saw no hiccups (the MS-II downloader, in case people don't know, does verification after sending the contents of the s19, so when it completes you know whether you have a good burn or not, and in fact which if any bytes failed to burn properly).
I pulled off the MicroInnovations and put on the TrippLite. Did two burns on the MS-II, again not a hiccup, switched back to the MS-I and burned -Extra two more times to it, not a hint of problems in any case.
Now this success is not surprising to me, as I've got the timeouts in both download and the MS-II downloader set to quite high values, which I believe allows any USB buffer flush to time out (although I saw no hesitation at all with either one, MS-II downloads looked faster than when I run just straight serial). Now I can't set these same values in MegaTune because it is interactive, and this would basically make it lock up if used offline. I'm rethinking my strategy of having a transparent off-line mode; if it were made explicit (File -> Work Offline) then I could raise the timeouts there, too.
