I have owned a trailblazer plus for some time now, and have set up
outgoing uucp to use various different speeds with no trouble at all
and no need to rewrite the eeproms.  On incoming calls the telebit
does automatic baud synchronization.  On outgoing calls it also does
automatic baud synchronization, and because I lack hardware flow
control I explicitly tell it that it should only accept answers at the
baud rate I want.

One more time: No write to the eeprom is necessary to change the baud
rate.

Writes to the eeprom *are* required to alter the default answer speed,
the answer tone issuance order, and a few default parameters.  None of
these should be overridden by a program except on a per-call basis.  I
have configured my telebit to reload the default saved parameters
(i.e. the ones I put in the eeprom) whenever DTR or carrier is
dropped, and have configured uucp to override the baud rate on a
per-call basis.
