I had a phone conversation a while back with the local Telebit Rep
about modem standards. He was relaying information from other sources
and was a little confused. So was I. Therefore anything I say here
should be confirmed or denied by those who really know whats going on.

Apparently CCITT is developing a more robust standard for 9600 baud
Async, full duplex, error correcting modems. They looked at a number
of proposals including Hayes's V series. What is now being proposed is
a combination of the Hayes proposal and the British Telecom one (both
use a Variant of LAP in their 9600 Baud modems).

As well the CCITT is now soliciting proposals for similar standards for
19.2K modems and Telebit has entered one. If their proposal is
selected they would have to a) place PEP in the public domain or b)
freely licence PEP.

Telebit is waiting for the results of the above efforts before they do
anything about adding more high speed protocols to the Trailblazer.
They are still working on other neat things similar to the G-protocol
spoofing.
  
So, if the information I was given proves correct the CCITT standards
which will emerge over the next year will AND Telebit's response to
them will determine if your Trailblazer is an Edsel. My past
experience with Telebit would indicate that it will not be.

[I apologize in advance for any falsehoods I may have spread here.
 I am not connected in any way with Telebit, nor have I recieved any
 bribes, kickbacks, or any other renumberation from them]
