If you happen to look at the System Manager's Guide (it came in Volume 3 of my small binders), Appendix A, it gives a complete step-by-step guide of how to reconfigure the system, INCLUDING a discussion of the format of the configuration file. In fact, if you'll look at page A-11, under A.6.3.3 Device Specifications, you'll find the following paragraph: The DHV-11 DZQ, and DZV-11 communications multiplexers accept a hexadecimal flag value to specify any lines that should be treated as hardwired with carrier always present.... That is to say, Ultrix as supplied DOES support modem control on terminal lines, but only if you have CONFIGURED it that way. The standard configuration is for hardwired terminals, not modems. Another way (kludge) is to wire your modems up so that DTR is always present. This is a REALLY BAD THING to do, but doesn't require you to reconfigure your system (if, as system manager / administrator you don't know or aren't willing to learn how to reconfigure your system - slight sarcasm intended - I don't know how somebody could get in that position without at least the willingness to learn). > I highly recommend that if at all > possible you find someone who has done a sysgen before to show you how. > Or if you're paying good money for DEC software support, call them up and > demand some assistance. Failing all that, try to get your hands on "Building > 4bsd Systems with Config" which is supplied with all Berkeley 4bsd systems. Yeah, right (complete sarcasm intended). That was ALL I got when I got a 750 and two distribution tapes of 4.2BSD dumped on my lap a few years ago. It was months before I had everything running reasonably well, let alone correctly. The "Building..." document wasn't all that helpful. And I NEVER got the modems stuff working correctly there either... -- Karl -- DDN: nyberg@ada20.isi.edu (formerly nyberg@isif.arpa) INET: karl@grebyn.com (probably won't work till 1 August or later) UUCP: ...!{decuac, seismo, vrdxhq}!grebyn!karl I don't need a disclaimer - I own the company!
