A colleague of mine needs to squeeze sound effects out of a PC using AT&T Sys V. Does anyone out in netland know of the src to a device driver that does such a thing? Or if he has to roll his own, what should he watch out for ? Thanks, Frank -- Frank D. Greco Crossroads Technologies, Inc. ARPA: frank5@mars.njit.edu P.O. Box 530 VOICE: (201)-754-7820

In article <2148@njitgw.njit.edu> you write: >A colleague of mine needs to squeeze sound effects out of >a PC using AT&T Sys V. ... Standard AT&T and ISC Unix have ioctl calls KIOCSOUND and KDMKTONE in the console driver. They drive the low-fi PC speaker about as well as it can be driven without doing tricks that take over the whole machine. You can play sequences of beeps of various tones. SCO recognizes the calls but doesn't actually make any sounds. Shameless plug: The Norton Utilities for Unix include, along with all the useful stuff, a program that plays tones on the speaker, specified either as frequency and duration or as musical notes. The new version even has a speaker kernel driver for SCO. Regards, John Levine, johnl@iecc.cambridge.ma.us, {spdcc|ima|world}!iecc!johnl

I'm now glad I didn't get the cdiffs finished; I'll have to port the kernel bell driver from Xenix (minimal, the startupcode has changed a little --- it works as is, but spits out its existence even with verbose=no) and put it back into the Makefile. ++Brandon -- Me: Brandon S.

We went from 2 filesystems running this on an ISC system to taking it off altogether because of kernal panics and hangs directly attributable to this package, and then the same on AT&T Unix. The same story from two other local sites. It is completely unusable. So, if you want to pay the money for a nice system that plays pretty tunes, be my guest, even though there was one for free posted to the net not that long ago. Disclaimer.... we got it as soon as it came out. It may have been improved by now... although I doubt it as I asked the person I reported the bugs to (he said at least one was known) to let me know when they were fixed and I have yet to hear back. -- Paul Guthrie chinet!nsacray!paul or pdg@balr.com or attmail!balr!pdg
