Quite some time ago I posted a procedure for blazer owners to test if their modems would start answering calls with PEP-tones-only if S92=1 and someone called the modem and hung up before establishing a connection. I would like to thank the people who responded. The results show that the blazer is very sensitive to the precise frequency which the phone company emits when the modem keeps the line off-hook after the caller has hung up. Some respondents were able to duplicate the problem while others could not. One person explained that his modem doesn't declare it a BUSY signal (as mine does) but rather a RRING!! So clearly the Trailblazer is being confused. The good news is that I finally convinced Telebit to open an MR on the problem. This was understandably difficult because they cannot reproduce the problem in their area. I asked the (very friendly and attentive) support person I was dealing with to call me if the status of the MR changed for the bad. It has been a couple of weeks since they accepted the MR and I've heard nothing. That's a good sign. It will be several months (at least) before the next firmware release, however.
