I am looking for small embedded ARM board with ethernet+USB+multiple
RS232+general purpose parallel I/O lines+multiple channel ADC+realtime clock
and capable of running Linux. (Am I sking too much?)
Do you know ARM board with these specs?

The new AT91SAM7X comes close, but no Linux. Other OS's however. See
www.freertos.org/portsam7xiar.html

Sorry, wrong link. This link shows the Ethernet and the USB on the SAM7X:

A Gumstix, plus an EtherStix and a Robostix or Audiostix expansion
boards would give you everything but the realtime clock. The serial
ports are TTL level though, not RS232. The Robostix board has on
on-board AVR which provides multiple GPIO and ADC, the Audiostix
provides fewer A/D and GPIO but saves you having to write for two
platforms (and you get audio - hence the name).

It is small (very small) and runs Linux out of the box.

You are being watched. This gives you power.

I like the Gumstix, but they only have USB client.

I just ordered a Linkxys NSLU2. While this would still need
something else for ADC and GPIO, it has Ethernet and 2 USB
ports. It also has 1.5 serial ports (one of them is read
only.

And yes, Linux runs on it.
