I'm still not quite sure why all the USB to Serial converters end in
9-pin male - so you need another cable to connect to pretty much anything.
Is there a reason why a null-modem configuration with a 9-pin female
isn't the norm? I can't think of one. 95% of people buying one of these
things probably wants that configuration surely.

USB to serial converter with a 6ft cable can be ordered directly from
the OEM of the chip for a reasonable price. See
http://www.ftdichip.com/Products/Cables/USBRS232.htm#UC232R-10. Just a
DB25 connector w/housing has to be fitted to it.

Thanks for the confirmation Don,
There was suggestion to use two low profile gender changers, one
male/male and one female/female to make it work on with he M100.
The $45 price tag is a bit steep. I'm not sure when it went up but
that was the closest thing I found to the perfect off the shelf
USB cable.

Hi Kurt,
I have one of these cables and yes, the housing is too thick
for the M100. It works fine for the 102 and 200.

I can't check all the details right now but I believe this
is the USB to db25 male null modem cable I posted about a
few months back. Though the price at that time was $25 not
$45.

Also, I think the housing is too thick for the M100 but
there was somebody on the list that tested it with both
the 102 and 200 and it worked fine.

If you were building one I would recommend an all in
one cable that hooks straight from a USB port to any
model t particularly the model 100 with no adapters
necessary.
Also it should be full null rather than defeating flow
control as the old complink cable did in order to
support programs like HTERM which rely on flow control.
And ftdi is the only way to go on Windows.
Maybe a very small pcb that can be built into a thin
hood shell with a surface mounted ftdi chip and max232?
All that said you could accomplish mostly the same
thing by simply aggregating the proper OTS parts and
software and offering it for sale as a package with
documentation. That way it takes out all the research
and guesswork and that's the real trouble.
