Well, it seems that there is something curious around there, I also get this return value. The code for me, has nothing to do whith "/dev/tty" and I use the ordinary getty, which does an open(the_dialin_device,... Everything works ok whith dialin, and dialout programs. Except whith uucico from Taylor-uucp 1.4, (kernel 0.99pl12. and alpha) I don't remember when this problem appeared, probably whith this locking devices, because before pl12alpha/pl12, the getty was killed immediately after the uucico call, (because sys_errlist[512] core-dumps...) and init was immediately respawning it proprely. I remember a thread about this I think... I have no time to trace that, I just looked quickly to MY problem :-) And this is what happens: The getty does "open("/dev/ttyS1", ... .At this time the open() call blocks until carrier detect, this is the correct behaviour of course. Now, uucico use the corresponding dialout device, and calls any hosts proprely. OK, No problem. Uucico exits. Getty is always on the blocked open(). Correct. Now, somebody calls, the modem answers and carrier is raised. Normally the open should be now effective... It is Not ! open() returns -1, and errno is set to 512 or 513, I don't remember the exact value. (I think it is 513, interrupt problem). Getty tries to syslog the error: error("/dev/%s: cannot open as standard input: %m", tty); Unfortunatly, sys_errlist[ 512 ] fatally core dumps, and the getty exits, and the user connected is immediately disconnected. The next dialin, after the respawn of a fresh getty by init, is correctly processed. This problems occurs ONLY whith UUCICO dialing out, whith other programs like MINICOM or personnal stuff the dialin/dialout works OK for me, and has been working ok for a long time... So, there is a problem either in uucico, either in the serial drivers, perhaps in the two pieces of code... And only whith them together. The LINUX serial devices work proprely whith other dialout programs, and this uucico code works ok under 386BSD and Sparc stations... But errno set to 512 or 513, this is true, I have seen it and I can reproduce it here when I want for now...

I don't think it is so difficult. After all you did write most of your response in tech-less English. And it was about computers, and it was not too difficult, was it? I think that most books for non-initiated in the Computer Wisardry lack a certain progressive teaching of the terminology.. Once that terminology is taught, one can get very precise in their books, and be fairly certain that the reader would understand... but maybe Computer Science is too young to have a stable terminology, and besides who would want to read an OS manual for the first to last page? It is a complex matter, and there are many things that should be done. Like, why not teach some of the jargon to kids, so when they grow up it would become an integrated in their language (if it is not already) and understood that a hard disk is not a floppy in a hard case. If things continue progressing as thy are, which they most likely will, the gap between those who understand computers and those who do not will become wider. And even in the new generation that gap will remain, even though people will not be as scared to use them (due to more powerful and easier to use Operating Sytems), because there will be relatively few people in the society who will be taught to understand them. Personally I look at Linux as an excercise, a very good one, that will teach me (and many other people) how to run, make and operate a good system. I will probably teach a lot of us how to make OS user friendly, be it through good manuals, or other important ways. Because I think of Linux as being an excercise on a large scale I think its accessablity to "outsiders" will be limited for a while ( I am not excluding a possibility that Linux will not go beyond that).

My four year old already operates Linux/Xwindows/twm tolerably. He certainly is not ready to install and troubleshoot it, but give him time. He can log in, type "startx", create and delete windows, exit, and logout. His favorite programs are roach, paint, and gas. Here therefore knows about pull-down menus, can read "OK" and "Cancel", can operate slide-bars (he taught my wife to use the center button for these), and probably some other things I am not aware of. The nice thing about Linux, as opposed to MS-DOG, Windoze, or Macintrash, is that I _don't_have_to_worry_about him_trashing_anything! The worst he can do is fill up the disk, or delete his .twmrc by accident (I keep a spare copy in my directory). My two year old did trash my CMOS once by cycling the power and banging on the keyboard too fast. I am thinking about hardware solutions to the power problems, and I am glad I wrote down the CMOS settings when I first installed the computer! - Larry Doolittle doolittle@cebaf.gov ------------------------------ From: furnish@dino.ph.utexas.edu (Geoffrey Furnish) Crossposted-To: comp.os.linux.help Subject: Re: X & ATI GUP Date: 26 Aug 1993 14:17:51 GMT In article <93238.093438KKEYTE@ESOC.BITNET> Karl Keyte, ESOC Darmstadt writes: From: Karl Keyte, ESOC Darmstadt Anyone got X running with the ATI Graphics Ultra Pro?
