Trailblazer Modem?

[Stewart]

As someone who has seen numerous references to the "Trailblazer" modem,
but not any description of what it is, I'd like someone to give a concise
description of what it's essential characteristics are.  How fast,
how expensive, how hooked to the UNIX-PC "system" (used with phone mgr.,
etc.), how dependable on "bad" lines.  E-mail would save others the bother
of seeing anything re-posted.  Thanks in advance.
