I'm curious - since I use these devices (USB serial ports) fairly
regularly - what doesn't work?

I can't get it to work with a program called GTROM Loader (a program
used for re-flashing firmware). I haven't tested whether it works for
more mundane tasks such as using Hyperterminal to let two PC's talk to
each other.

Could I ask what model you use? Or could you even point me to the
relevant link on eBay? Here's the particular one I bought:

http://cgi.ebay.ie/USB-To-Serial-COM-RS232-DB9-DB25-Cable-Adapter-UK_W0QQitemZ250258189245QQihZ015QQcategoryZ41995QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

but it just plain doesn't work. I paid 5euro for a device off eBay
which lets you hook up IDE hard disks via USB, and it works absolutely
perfectly and it's lightning fast, so I don't see why I shouldn't be
able to get a USB to RS232 adapter for dirt cheap that works.

Are you certain that your own device(s) can do every serial port job
perfectly?

Keithy, weithy, please shove it directly up you know where.

What right do you have to interrupt a perfectly sensible, rational
conversation?

Also, you might want to google the term "killfile". It might help.

I make no claims one way or the other. I've heard that the USB
emulation of serial (and parallel) ports doesn't really work, but IMVLE,
it seems to work OK. So, I really am just asking out of curiosity.

As I said, I've done only very little testing; it sounds like you've
done quite a bit more with it and I'm curious as to which things don't
work. I've never heard of GTROM, of course.

(I know this must be hard to believe, this being CLC and all, where any
question of the form "What makes you think that?" is loaded with so much
hatred and venom and a clear implication that you are friggin' out of your
mind...)

I wouldn't know - all pretty much generic - I do know that I've been
playing with 3 of them lately, and, as I said, they all seem to work OK.

No, not at all. See above.
