Put a breakout box between an MT-80 or MT-90 and the Lantronix. Full 
25-pins connected, watch the lights when they are talking.

Do the same with the MT-85. Any differences? Pins pulled up, or down, 
that aren't with the '80 or 90?

ATP is just three pins - sometimes devices need their CTS pin, or 
whatever, pulled up before they'll talk, and TX/RX/GND isn't enough.

What does the MT-85 manual say about how you connect it serially? Any 
significant difference from what's in the '80 or '90 manual?

What do Tranzact say? I don't know how it goes over the pond, but here 
in the UK, we expect the vendor to step up when their promises go 
bad.....

Going back a ways, Alan Yeo and I used to debug the more intractable 
serial stuff with an MS-DOS program and a special cable, so a PC could 
sit in the middle of the link and tell us what was going on, for all the 
world like a super breakout box rolled up with a 90's progenitor of 
Wireshark.

Wonder if he's still got it somewhere? :-)
