Hi, We have Santa Cruz Operation's Xenix 2.2.2 running on our model 80 PS/2. I hacked the generic Hayes HAYES.C or whatever it was called dialer to send the porper initialization string for the trailblazer and also changed the expected return strings in a few places. It was really only about two hours worth of effort. I are an engineer, so an experienced software craftsperson could probably do it quite quickly. I made a separate dialer for each baud rate at which the Trailblazer was to be used, with corresponding entries in the L.sys file. Ultimately, we talked SCO into giving us Honey DAN BER uucp, which is only minorly buggy. I don't know who to contact at SCO, but they do have HDB available if you prod around some. I guess I should clarify that the bugs aren't serious, being only that silly values for xfer rates, etc. appear in the log files. The g protocol and dailer software seems OK. HDB makes supporting unusual modems, such as Trailblazers, much less hassle. In some ways, the latest generic System V modem cap way of doing things is better than HDB, as it has the advantage of database modem descriptions a la HDB. Sys V also allows limited branching in the dialer script, thus permitting more explicict results to to posted to stderr (and thus LOGFILE too). Alas, Xenix doesn't seem to have picked this AT&T "feature" up yet. Hope this helps, Bill PS: the map file for us is way out of date, try a path like: ...!spl1!neoucom!wtm
