Hi All,

You need a USB host controller system with an OS that can enumerate USB,
and you can get source or drivers for the platform.

There is no such thing to "convert" a USB device to something else in a
simple way.

If it were me, I'd find a phone that has standard RS232 signalling.

No. These are _slave_ devices. They won't do what is needed here (he needs

These are complete 'built' assemblies, based on the Vinculum chip, which

will do what he wants (the phone is only seen by the PC as a 'comm'
device). However the chip alone, is about 1/3rd the price, and he has
already asked for something cheaper!...

Hi Roger,
second one I listed is the chip itself, and the first one, the module, I
gave as an example for him, to enable him to understand what is required.

However the chip alone, is about 1/3rd the price, and he has

yes I know, and I listed the IC, but won't if cost him more than the
price of a chip, and devise a means of somehow hooking up to an IC and
I/O connectors, and get it running?

reality is, for a one off, you would be lucky to do it cheaper, let
alone the time involved it getting it all running.

But if he can, fine! :)

I gave him all the options to look at in the Vinculum family, and make a
judgement based on having the info at his fingertips.

Cheers Don...
