I have a client who needs to write program hex files to flash in installed

complicated for a civilian.
Would anyone like to share experiences with simpler software, possibly
Windows-based? Recommendations for interface hardware, software packages,
etc.?

Simplest and cheapest is H-JTAG with an Olimex Wiggler clone. Not a lot
of bells and whistles, tho. H-JTAG is free; the clone is cheap.

It wants a real parallel port, though.

Thanks. That's one of the packages included in WinARM, of course. I'll
set it up and give it a run.

A step up is the Scarabeus debugger package and usbScarab from Kristech.
It can also use the Wiggler.

I generally use the NoICE debugger along with a Segger J-Link USB pod.
Very quick and easy to connect/burn/trace/debug. A nice package but
kinda pricey. Using the RDI capability of H-JTAG, NoICE will chat with
the chips through the Wiggler (or clone) if you have a parallel port.
