Their phone number in Calif. is (408)986-0566. Also check out their transciever with excelent diagnostic LEDs built-in standard.

Helios is located in San Jose, CA.

I would appreciate it if someone could tell me where to find it. v6n48 had a few tidbits on the QIC format -- in two messages from K. Richard Magill and Ron Hitchens. These were sorta side notes, however -- just enough to whet your whistle. Since Sun went to QIC-24 format tapes for their distribution, they have paid a little more attention to documenting the format. Try page 84 in the "System & Network Administration" manual in the 4.0 distribution manual set. That's not much detail either, however. It's a start. -- Mike Mike Jipping Hope College Department of Computer Science jipping@cs.hope.edu ------------------------------ Date: Fri, 1 Jul 88 11:16:34 EDT From: Edward L. Lafferty <ell%linus@mitre-bedford.arpa> Subject: Re: what does a vt100tool do Reference: v6n122 More important than the double height stuff is the fact that the emulator acts like a vt100 to the remote host, for example, when the remote host queries (electronically) the terminal as to its type, the emulator sends the correct escape sequence for a vt100. The shelltool will not respond correctly and many systems (DEC based, especially) will refuse to work since they depend on the fact that the termnal is a vt100.

All that is required to do this is login or rlogin access under any user id. The cure, if you want to take lockscreen seriously, is to set "mesg n" on each and every window.

I have just installed SunOS 3.5 and I am having two types of related problems. 1. When I bring up suntools and try to open up four shelltools the last opens with the message "out of swapspace cannot continue". If I have two windows open and try to open dbxtool it either ignores the request or prints the message in the console window: pr_make from fd error: valloc failed pr_open pixrect create failed for /dev/fb window subwindow creation failed could not create window All this happens on the server. suntools has no problem of the same sort on the clients which have the same amount of swap space. Why is this happening and how can I fix it. 2. Ok so I thought some additional swap space on the server might help. I repartioned the disk to allow sd1d to be a swap area in addition to sd0b. Now the manual implies if you add a line to fstab saying: /dev/sd1d / swap ignore and in rc there is an execution of swapon -a the entry in fstab will make sd1d a swap partition. Do you also have change the line in the kernal conguration file to: config vmunix root on sd0 swap on sd0b and sd1d By the way at no time could I detect through vmstat -S that the swap area was bein used up. How can I tell if sd1d is really being used. The behavior of suntools is essentially unchanged on the server even when the swap area is supposidly doubled. I am confused. Can someone help. Mail answers directly to me. I will sumarize on the net if the answers seem of general interest. [[ Aaron later sent me this followup message: --wnl ]] Evidently there really was not enough swap area. But the line in /etc/fstab should look more like: /dev/sd1d swap swap sw 0 0 which the second argument (the first swap) is probably ignored. Also the kernal must be reconfigured with somthing like. root on sd0 and swap on sd0 and sd1 and sd1d It is not enough to change the fstab and then type: swapon -a. If you do you get a message like: /dev/sd1d not a device. I can't find this in any manual. If somone knows where it is I would sure like to hear about it.

The following runs on Sun-3 but not on Sun-4 since the Sun-3 is byte addressable whereas the Sun-4 is not. Folks doing things like communication packages where there is lots of encapsulation going on should probably not plan to just compile and run. struct a { int b; } main() { struct a *c(); c()->b = 1; } struct a *c() { return((struct a *)((char *)malloc(sizeof(struct a)+1)+1)); } [[ I'm not surprised.

I recently set up a Mac user on our Sun. She was used to being able to print text by using the mouse, so to make her feel at home, I added the two commands "print selection" printSelection "show selection" showSelection to /usr/lib/rootmenu (and my ~/.rootmenu). Both commands are one-line shell scripts: #!/bin/csh -f -e # print current text selection echo "" | cat /tmp/winselection - | sed 1d | lpr -h #!/bin/csh -f -e # show current text selection in a Suntools vi window shelltool -Wh 10 vi /tmp/winselection I find them handy, hope others do, too.

So now we have 25 Sun 3/50's with 68881's, and 3 260/280 machines with FPA's. After some testing, it appeared that the FPA boxes would also run code compiled with -f68881 (altho they don't use the FPA). So in a valiant attempt to speed things up, I re-compiled the X11R2 library with the -f68881 option. Now, whenever I try to link against this library, I get a ld diagnostid 'Undefined: f68881_used'. What puzzles me is that the "Floating Point Programmer's Guide" (800-1552-10) states at the bottom of page 5: "An executable program composed of severally independently compiled modules can contain only one kind of in-line hardware floating-point. ... Although the practice is not recommended, you can link together modules compiled with -fsoft, -fswitch, and any one type of in-line hardware floating point." The library is compiled -f68881, the program is defaulting to -fsoft. So why do I get the diagnostic? (For those who care, I learned my lesson and recompiled X11R2 with -fswitch. And next time I won't compile stuff at 2AM, from home, without manuals :-) Valdis Kletnieks Sr. Systems Programmer Clarkson University ------------------------------ Date: Thu, 30 Jun 88 18:00:16 EDT From: Jeffrey A.

I put one up and got it runnin but need to edit the /etc/hosts, and passwords and clock, but I can't get into the root directory to do so! I tried logging in from the boot screen as "root" with no password, with the domain name as the password, and with the machine name as password. I tried su with no account and with root as the account in all of the above permutations. I have had a call in to Sun for a few days, but we can't hook up, as I am seldom in my office. How the heck to I get into the root to make everything better? Help!

Kim <cck@cunixc.cc.columbia.edu> Subject: getting ethernet address of a physical interface? Does anyone out there know how one retrieves the ethernet address of a physical interface under SunOS 3.x or 4.0? (Actually, most interested in an answer about 4.0). The information is useful when building protocol drivers on top of the NIT facility. Please send replies directly to me. I will summarize and repost to sun-spots at a later time. Charlie C.

I am interested in grabbing and reproducing sound (mainly speech but music as well) on a sun3/60. Our sun man doesn't know of any available sw/hw for performing this task. If anyone in netland has looked at this could you mail me your results. Sound quality is not very important, a sample rate of 15 khz would do, and of course the cheaper the better. I don't want to spend time putting my own board together or writing comms software to controll a PC via RS232.

Mazer) Subject: Courier fonts and troff? Two questions about troff: 1) Is it possible to use the Apple Laserwriter Courier font from troff? (We can already kludge the Postscript output file to substitute the Courier font for one of the standard 4 fonts, but is there any easier way?) 2) More generally, is it possible to embed postscript commands in troff text source? From within troff text, we tried to use \!_postscript_commands_ but the Laserwriter just printed the _postscript_commands_ as ordinary text. -- Alan ..!cit-vax!elroy!alan elroy!alan@csvax.caltech.edu ------------------------------ Date: Thu, 30 Jun 88 14:36:12 EDT From: Kerien.Fitzpatrick@cive.ri.cmu.edu Subject: using lpr for plot spooling? Has anyone used lpr as a means of spooling files to a plotter? We have a Draftmaster II [Hewlett Packard] and the spooling software that came with our software package is primitive at best. What I would like to do is to use lpr to spool the files to the plotter. Does anyone know if this is possible and if it is - how difficult would it be [do I have to write an output filter?]? Any info as to reading material, etc. would be appreciated.
