ethernet-to-serial gateway |
|
|
Hi,
I'm looking for ethernet-to-serial gateway (1 eth port, 1 serial port).
The device must support DHCP and link state change on eth0 (auto renew
ip address from DHCP server). I'm testing tibbo DS202 and Wiznet EVB8051
but this doesn't works.
Regards

If you want to build your own product you could use a development board
with an ARM processor and an ethernet chip.
http://www.embeddedartists.com/products/boards/lpc2138_100eth.php
You just need to create your own firmware.
Another possibilty could be the boards from
www.rabbitsemiconductor.com

Comtrol has a 1-port gateway. IIRC, it doesn't renew the DHCP
lease on link state transitions, but you can get a development
kit and modify the firmware to make it do so.

Looked at the Xport from Lantronix?

I've looked at Tibbo Em202, Digi Connect-ME & Wi-connect, DPacTec
Airborne and gone for the Lantronix XPort & WiPort. I spent som
time on the em202 first (climbing the learning curve on co
redirectors, and then bypassing them and trying to connect directl
using tcp/ip). Ultimately, I gave up on the em202 because I couldn'
get it to go properly in a client/server mode, and comparison, th
Digi & Lantronix modules worked properly. The Lantronix WiPort i
cheaper than the Digi Wi-ME and the tech support in the UK is better
The detail on the em202 is that if the PC/virtual com port end is th
slave, it has to poke the link first to get it to start up :!:
which was no use if the cable got disconnected and the micro wante
to notify the Pc that it was connected again |

Where does the TCP/IP stack it ported from? |
I wish I can use a FreeBSD TCP/IP stack in this device.
On the otherhand, does anyone know that this device support RTEMS ?
Thanks
Sam

Did you find any practical / cost effective solution for the

Five years ago I configured a FreeBSD machine
as a gateway for a cable modem. One of the machines
connected to it was an Amiga using PPP and DHCP
on a serial port at 115200.
These days, if I needed it, I would use a
fanless mini-itx board and FreeBSD.

That sounds like massive overkill (and a lot of work) for most
of the applications I've see for 1-port gateways. For less
money you can get a 2"x3" board that already has the needed
firmware in flash and requires about 2W of power.

True.
I made the original FreeBSD gateway because I had an old
Pentium 75MHz board ready to be thrown out - replaced it
with a Linksys when I grew tired of the noise and didn't
need the Amiga connected outside.

Robert, you asked

It lets you use Microsoft's Mscomm to talk to it, rather than Winsock
which is harder. However, if you're planning to use lots of thes
devices, you'll need to install a CPR for each device, which (
think) means longer boot times and the other ramifications of
longer device driver chain
So you have to go winsock sooner or later |
