I assume your TrailBlazer is accepting commands (otherwise how do
you manage to dial out?), in which case the lack of a response is
simply a matter of getting the right setting for Qn.

As for calling a TB+ with S92=1, you need to set S50=255 in the
chat script for calling that system.  You may also need to increase
the time the modem waits for a carrier (S7) and the time uucico
waits for a response, e.g.

    ATQ6X1S50=255S7=60DTnnn FAST-\c-FAST ...

(The Q6 and X1 set things up so you get a "CONNECT FAST" result
code for the call if it connects.)
