I've had the best success with the UDS-10 when I've used my Atari to set it up through the RS232 side, rather than the ethernet side. Here's what I do:
1. Load a term program on the Atari (Bobterm and DeTerm are the ones I've used).
2. Set the term program to 9600 baud, ASCII, full duplex
3. If the UDS-10 is set to its default parameters, you should be able to "talk" to it through the Atari.
4. Cut the power to the UDS-10 and hold down the Atari's "x" key (in lowercase), and reapply the power to the UDS-10 while keeping the "x" key pressed. This puts you into the UDS-10's configuration mode.
5. From there, I use the following parameters:
In the Server Config menu (option 0 on the configuration menu):
IP Address: 000.000.000.000 (this sets up DHCP on the UDS-10)
Subnet Mask: Match the one on your router
Gateway: Use the router's IP address as your gateway.
In the "Channel 1" settings:
Baud: 9600
I/F Mode: 4c (this configures the Lantronix to work with RS232--I think it's a default configuration)
Flow: 00
Port: 10001
Connect Mode: D6 (this sets the Lantronix to emulate a Hayes-compatible modem)
Remote IP: 0.0.0.0
Remote Port: 0
Disconnect Mode: 00
Flush mode: 00
Disconnect Time: 00:00
Sendchar 1: 00
Sendchar 2: 00
Under menu item 5, "Expert":
TCP keepalive: 0 (disable)
After you complete these settings, you should be able to save them and start using the UDS-10 like a modem.
Make sure to use capital letters in your modem commands, with a space before the port number, like this:
ATDT 24.125.190.196 23 (this should connect you with The Boot Factory)
ATDT 82.169.239.74 23 (this should connect you with The Atari Inside)
ATDT 84.24.93.15 471 (this will connect you to Thunderdome)
You could also type:
ATDT024125190196/23 for the same function.
Since the UDS-10 needs IP addresses to connect to BBSs, you may need to ping The Boot Factory, The Atari Inside, and other BBSs if their IP addresses change.
I have a little trouble sometimes getting my router and my UDS-10 to sync up so that I can call out. Usually powering them off and back on again does the trick. If you can't connect, try that. Also, be careful as you're typing the dial out commands. The way I understand it, your command won't work if you make mistakes and ahve to use the backspace key.
Lastly:
After your UDS-10 has been set up to emulate a Hayes modem, you can reset it without unplugging it. When I want to fiddle with my UDS-10's configuration, I use the "ATD" command by itself, which puts me into a utility mode. From there, "QU" allows me to exit the utility mode, and "RS" allows me to reset the UDS-10. (Make sure to use capital letters when you use those commands.) If I type ATD to get into utility mode, then type "RS" (without hitting return), then set the caps to lower case, then hit enter and quickly start holding the "x" key, the UDS-10 will reset and go into the configuration mode outlined above. (This saves me from unplugging the UDS-10 while trying to reach my Atari keyboard when I want to look at the configuration.)
Good luck. Let me know how it goes. I'm sure you can find a UDS-10 manual at the Lantronix Web site.
