Did you check out the /usr/include/sys directory?

You'll probably find more "gotchas" in the scripts when you start to
receive news and post news.

I have exchanged mail with Henry Spencer, at the time that we decided to
put CNEWS on piggy and at MWC BBS.  He does not want to put in any
Coherent specific changes.  CNEWS is considered to be generic UNIX, and you
just have to adapt it to your system.  Also, if you decide to distribute
your version of CNEWS, it must contain a disclaimer that it is not the original
CNEWS, and that Henry and Geoff are not responsible for any problems found.
Also, the current Coherent CNEWS comes with an installation script, written by
Rick Nickle, that makes it easy to configure and use on Coherent.

I have all the patches through March 1991, and I will be upgrading the
current Coherent CNEWS pretty soon.

Yes, the screen blanker only works with Hercules and Mono adapters.
