People who have Telebit Trailblazers with anything earlier than the BA4.00
firmware should upgrade. Apart from a striking improvement in interactive
response (see comp.dcom.modems for my comments on this), 4.00 appears to
fix an annoying bug in which the modem occasionally thinks it's off-hook
when in fact it is on-hook. If you have +++ recognition disabled, the
only way to shake the modem out of this state is to power-cycle it.
The firmware upgrade costs something like $99/modem normally, but given that
this problem is a legitimate bug, if you're willing to go via California
and wait a few days, you can get the new ROMs free. (At least, if your
Trailblazers are still in warranty, which most will be. Actually, the way
it works is that you get the new ROMs and they'll bill you unless you send
the old ones back reasonably promptly.) You'll need someone who is at
home enough with hardware to change socketed chips, and he preferably
should have a suitable extraction tool, because those sockets really have a
death grip on those chips.
