Are you really or do you want the Basically because I've been considering getting an HF rig, and haven't had much luck with voice modes so far. The local repeaters tend to be gathering grounds primarily for people who already know each other, and while they aren't actively unfriendly to newcomers, don't go out of their way to respond/welcome them. And I can't get to know them through the clubs since they are on nights I'm unavailable. I was also curious. I knew HF packet existed, just didn't have many details about it. What it took to run it, etc. Bob ------------------------------ Date: 16 Sep 1994 21:38:46 GMT From: dog.ee.lbl.gov!overload.lbl.gov!dancer.ca.sandia.gov!cronkite.nersc.gov!fastrac.llnl.gov!usenet.ee.pdx.edu!news.reed.edu!gaia.ucs.orst.edu!news.uoregon.edu!vixen.cso.@ihnp4.ucsd.edu Subject: KPC 9612 To: ham-digital@ucsd.edu I am interested in knowing more about the KPC9612.

I think it was written by Johan ( Hence the J ) Reinalda, WG7J ( Maybe thats the reason for the J) and a couple of other fellows. You can also work the x.25 protocol from this program.

Most people who only > have access to small machines like a PC or Mac don't have this luxury. Not so. We run SVr4 Unix on several 486 clones. These machines handle 50 telnet users and a heavy NFS load. They run weeks, sometimes months, without a glitch. When they do go down, it is usually because we take them down to modify something or install a new driver. There's no reason why "most people" can't have this luxury too. > Many of the Unix implementations don't have or use the MMU (memory > management unit) which gives Unix this capability. You are wrong on two counts. Modern Unix implementations on small computers "do-so" use MMU hardware when available. But hardware support of memory mapping is not the reason Unix is stable. Protected addressing and the clear distintion between trusted kernel device driver code and user code is the reason for the inherent stability of an OS. > > This is my current crusade.
