Another solution would be the "ARM Industrial Module AIM 711", which
is running eCos as OS. It has one ethernet and a serial interface.
Look at
http://www.visionsystems.de/arm7.html
for further informations.
Best regards,
Roland
On the WRT54G V2 there is 2 ttl level Serial ports inside , all you
need to add is the MAX232 (233) , they are on pcb board on an
unpopulated plug , 2x5 pins like a jtag plug (needs to be soldered in
also).
It contains a 200Mhz MIPS , but no means of interfacing a disk or
Flashcard

Hi Udo,
Lantronix has a small RS-232 <-> Ethernet Converter which has almost the
size of a RJ-45 connector, called XPort
(http://www.lantronix.com/products/eds/xport/index.html).
Important: You don't need to care about the kernel, the compiler and so
on. I think it's a good solution if You don't have a big amount of data
to transfer.
I know that there is also a similiar solution including a Net+Arm chip,
which is completely user-programmable (except bootloader).
I hope this helps,
Michael

Perhaps the linksys routers are something for you.
http://www.batbox.org/wrt54g-linux.htmlhttp://openwrt.org/
Cant find it right now, but I seem to recall that 2*RS232 was
available on the inside of the box, not as external connectors.

Just to make it clear: I just need a linux embedded module with a linux

Hello everybody,
can somebody suggest me a embedded linux module with RS232 and Ethernet
interfaces? Not much more is needed.
The RS232 interace is used to attach a GPRS modem module.
I want to use one of the following configurations:
1 - FTP server for the ethernet side, upload then via GPRS to another FTP
server
or:
2 - daemon that loads a FTP file from the ethernet side and then uploads it
via GPRS
As you see, that should be a Ethernet<->RS232 gateway for a ethernet client
that doesn't understand PPP.
I searched on linuxdevices.com and google but simply can't find a device
simple and cheap enough to match my needs. There are too many out there...
Thanks for any response!
Udo
