I received my Lantronix UDS 10 on Wednesday. And, I was finally able to get it to talk to my TI-99/4a using TIMXT terminal emulator.

The server settings come out of the box setup for DHCP. But the Channel (option 1) settings need to be modified to put the device in Modem emulation mode. While I was at it, I turned off flow control, and set the baudrate to 4800bps to match the defaults in TIMXT. Below is a transcript from setting it up with via telnet:

Change Setup:
  0 Server
  1 Channel 1
  5 Expert
  6 Security
  7 Factory defaults
  8 Exit without save
  9 Save and exit            Your choice ? 1

Baudrate (4800) ? 
I/F Mode (4C) ? 
Flow (00) ? 
Port No (10001) ? 
ConnectMode (D6) ? 
Auto increment source port  (N) ? 
Remote IP Address : (000) .(000) .(000) .(000) 
Remote Port  (0) ? 
DisConnMode (00) ? 
FlushMode   (00) ? 
DisConnTime (00:00) ?:
SendChar 1  (00) ? 
SendChar 2  (00) ? 

Others have it working with flow control, and with port set to 23. I need to investigate why port 23, and how am I wired wrong that I cannot get flow control to work.
