How much of the RS-232 stuff do you need? Do you need just Rx/Tx or do
you need the full blown handshake lines also?
I'm playing around with an old Netgear WGT634U home router that runs
Linux <http://www.openwrt.org>, has serial ports, ethernet ports, and
a mini-PCI slot for the radio. You wouldn't need the radio, so maybe
you could pick one up cheap. The serial ports are Rx/Tx only, no
handshaking and are 3.3 Volts. You would also need a tiny RS-232
converter like the one here:
<http://www.compsys1.com/workbench/On_top_of_the_Bench/Max233_Adapter/max233_adapter.html>
Other routers like the Linksys WRT54G will work as well.
I'd be willing to help you with this if you want.
That's a great idea. It would be way cool to just use a small appliance
like that. I don't need any of the handshake lines, just RxD and TxD.
I've used the Maxim RS-232 converters before and am familiar with them.
If you've got 2 serial ports, you can use a cross-over and loop back on
yourself, and use netcat to transmit the data over IP to another netcat
that does the same thing. But if you have the ability to run netcat, you
prolly have the ability to use the Serial-over-IP software and create a
fake STTY for it
