Roberto,
The Link-HUB-E is exactly what you wished, a serial adapter married with an
ethernet/serial connection. Embedded Systems also makes a similar product,
the HA7E.
I believe that these companies have found sending raw serial data over the
network works poorly -- the DS2480B is too fussy. Instead they use a simpler
ascii serial protocol ("r" for reset, "f" for first device, "n" for next,
...) which can be less efficient, but is certainly more robust. I have
support for these protocols in OWFS and make the substitution transparent
(just like substituting the USB for serial adapter is transparent).
LINK also sells the bare chip for OEM use -- perhaps that would be the
easiest way if you are eager to build your own.
If you want to create another microprocessor with a simple interface, and
put the design in the public domain, or commercially available, I'd be happy
to help and support it.
