Becker) ---------------------------------------------------------------------------- From: epoole@leotech.mv.com (Eric Poole) Subject: Prog. in C for Linux = ?? Date: Sun, 15 Aug 1993 20:17:00 I'm a pretty respectable C programmer for MessDOS stuff and embedded systems, but don't know how to write programs for Linux (or other *nix) systems. Can anyone offer suggestions for books to buy and read that will explain the ins and outs of this? I need things like where to put stuff (e.g. sources here, .h files there, libs over there), how to use make and the structure of the makefile (I typically use that Borland C++ IDE crutch so don't know the structure of the typical makefile, and the times I have used make, the makefiles were all different) ... also need info on *nix library calls and such. I need this for general information, but for short term needs ... I have my DOS BBS connected to the Linux box through serial ports, and I want to set it up so that someone can telnet in and access the BBS through the serial port. This involves writing a program that is executed from a login shell (I also don't know how to write login shells but have some books that will probably teach me that) that will signal the BBS, respond while the BBS (which thinks it is talking to a modem) answers, then ties BBS and caller together. As such, this program will have to act like a modem ... e.g. toggle the Ring Detect line, look for the ATA from the BBS (on this system the BBS takes care of taking the modems off-hook, the modems do not auto-answer), then raise Carrier Detect and complete the connection. So, I need enough info (from books or wherever) to enable me to write this program and make it work under Linux. Please respond either here or (preferably) by e-mail to epoole@leotech.mv.com, and I'll summarize any e-mailed responses.

People are going to use what they like to use, and if they're lucky, they're going to keep an open mind about other tools. I've not learned TeX yet, although I'd like to. I use WordforWin for most of my schoolwork, and I use it like this: I write the whole document in a basic font, such as Times 12, and then go back and modify the fonts, weights, etc., when I'm done. I like being able to see how the document is basically going to look as I'm writing; I like to "drag and drop" (yeeck) tables and fill them in using the TAB key to switch from field to field. It's just more convienent right now.

Date: 11 Aug 1993 13:38:34 GMT What I don't understand is this need for people to compare Linux with SCO/WNT/BSD/etc. in a "mine's better than yours" attitude. Why did the comparison with SCO even come up? And why this attitude about Linux becoming a commercial competitor? I don't think that Linus's motivation for creating Linux was to create something that was ing to go head-to-head with commercial OSs (although I can't speak for him); I think he just wanted to see if he could do a Unix of his own that would be a very quality OS that he and other people could use.

Spork (halgrim@diku.dk) wrote: > Except when logged in as root, no disk writes are acceptable > on my Linux .99. I would guess it's a permissions problem. Users have to have write access to create or write files or directories. As root, try making a temporary directory in your root dir. Then do a "chmod a+rwx" on it. Then try making some files here as another user. Example: mkdir /tmp0 chmod a+rwx /tmp0 If this works, I'd recommend that you get a general unix book and read a little more on the general aspects of a unix file system. You can also checkout the chmod man page. It could also be a quota problem. I didn't think it was implemented in linux yet, but it is possible to limit the amount of space each user can have on the disk. I would assume root would be immune to any quotas.

There are 18 sectors/track. ie 90 sectors/sec . therefore the transfer rate is 512*90 = 50KBytes/s (aprox.). Negligable as far as DMA latency goes. I see no conflict in the refresh DMA(ch0, highest priority) leading to 'byte' robbing of the FDC DMA, even with no buffering on the FDC. Ie 2 Competing DMA channels * 1uS/transfer << 1/50KBytes/s. How else can a IBM PC(4.77MHz) work with a FDC? As stated, DMA on post-IBM AT class machines doesnt exist, the memory controller subsystem does it transperantly. Get a refresh tweaking program or disable the refresh channel on the 8254 and your computer wont crash. Test the CPU landmark speed, you'll see no difference (try it, i havent, should be interesting). Lets face it, the architecture works (except for some CT chipsets that have buggy 16 bit DMA, which doesnt concern the FDC). In general, hardware is the natural scape-goat to blame for software bugs. Even if there was a problem, i wouldnt change the DMA setup given all the near-8237 chipset clones floating out there, just to much incompatibility to risk anything that isnt cosher IBM BIOS. ------------------------------ From: becker@super.org (Donald J.

To avoid any misunderstandings about the 3c503, I'll clarify a few points: The 3c503 does not have "EEPROM setup", so the diagnostic/setup program isn't needed before running the card with Linux. (Some other ethercards do have EEPROM setup, and you may have to run their MS-DOS EEPROM setup program if you don't like the defaults. Linux has a released version of 'wdsetup', and alpha versions of 3c509 and NE2000+ setup programs.) The shared memory address of the 3c503 is set using jumpers that are shared with the boot PROM address. This is confusing to people familiar with other ISA cards, where you always leave the jumper set to "disable" unless you have a boot PROM. The IRQ line is set in software, with no hints from e.g. EEPROM. Unlike the MS-DOS driver, the Linux driver has capability to autoIRQ: it uses the first available IRQ line in {5,2,3,4}, selected each time the card is 'ifconfig'ed. (Older driver versions selected the IRQ at boot time.) The ioctl() call in 'ifconfig' will return EAGAIN if no IRQ line is available at that time. The Linux 3c503 driver will with the 3c503 programmed-I/O mode, but this is slower and less reliable than shared memory mode. -- Donald Becker becker@super.org Supercomputing Research Center 17100 Science Drive, Bowie MD 20715 301-805-7482 ------------------------------ ** FOR YOUR REFERENCE ** The service address, to which questions about the list itself and requests to be added to or deleted from it should be directed, is: Internet: Linux-Activists-Request@NEWS-DIGESTS.MIT.EDU You can send mail to the entire list (and comp.os.linux) via: Internet: Linux-Activists@NEWS-DIGESTS.MIT.EDU Linux may be obtained via one of these FTP sites: nic.funet.fi pub/OS/Linux tsx-11.mit.edu pub/linux tupac-amaru.informatik.rwth-aachen.de pub/msdos/replace The current version of Linux is 0.99pl9 released on April 23, 1993 End of Linux-Activists Digest ******************************
