Shows you what a good idea sticking an AFAIK in there was. I stand
corrected, thank you. That constant exists both in 2.0.* and 2.2.*
kernels, with values 15 and 20 respectively for x86. Where do I find

Hi.
We installed RH 5.2 on a Compaq Deskpro (PII 300) and upgraded to
kernel
2.2.2 as we needed support for serial ports with IRQ sharing. Since
the upgrade
we notice frequently in /var/log/messages problem about the root
harddisk
like this "hdb: lost interrupt" and then a reset sequence. This slow
down
the box a lot.
We disabled (U)DMA with hdparm in the hope it was something
related with bus-mastering but nothing changed.
Is it a know 2.2.2 problem or is the hardware broken ?
dmesg:
hdb: lost interrupt

I have a *very* old text file that was one of my very first BBS downloads
in 1982 or so. It has a line very similar to this.
OK, I just dig it out from an Apple // 3.5" ProDOS disk. A quote:
Some of the concepts in these Xerox editors have been
incorporated into editors running on more reasonable operating
systems- EMACS and VI being two. The problem with these editors
is that Real Programmers consider "what you see is what you get"
is just as bad a concept in Text Editing as it is in women. No,
the Real Programmer wants a "you asked for it, you got it" text
editor- complicated, cryptic, powerful, unforgiving, and danger-
ous. TECO, to be precise.
The document is called "Real Programmers don't use Pascal". It extolls
the virtues of mainframe FORTRAN. It's actually quite funny, and is also
quite a "time capsule", as it appears to have been written in 1982 or so.
I can upload it here if anyone is interested.

A serial port is a file (everything in UNIX is a file), and you
read from serial ports just as you would from any other file:
port = open("/dev/ttyS0", O_RDONLY|O_NOCTTY);
read(port, &buffer, 1); /* Read one character, blocking read */
close(port);
Add O_NDELAY to the open flags to get a non-blocking read; you'd
use this to check if a character is waiting (read returns the
number of characters read). You can also use the file descriptor
("port") in a select() statement, in conjunction with file descriptors
representing sockets, pipes (and even disk files).
Modifying tty parameters is done though the ioctl interface
(TCSETA, TCGETA). To set the baud rate and other parameters,
proceed as follows:
#include <sys/ioctl.h>
#include <termio.h>
struct termio ttypars;
int ttyspeed = B38400;
int ttybits = CS8; /* Eight data bits */
int ttystop = 0 /* One stopbit */
int ttyparity = 0; /* No parity */
ioctl(port, TCGETA, &ttypars);
ttypars.c_lflag = 0;
ttypars.c_oflag = OPOST | ONLCR | TAB0 | CR1 | VT1 | FF1 | OFILL;
ttypars.c_iflag = ICRNL | IXON | IXOFF;
ttypars.c_cflag = CREAD | ttyspeed | ttybits | ttyparity | ttystop;
ioctl(port, TCSETA, &ttypars);
Check the termio man page for details.
Take care,

Hello
I have upgraded from 2.0.35 to 2.2.2 and have lost printing
capabilities. I have read the changes documentation to no avail. I know
that lp1 becomes lp0 but my system fails to recognize this change. Any
way or command I must do so the system suse 5.3 will see the lp0. When I
try /proc/ioports it gives a permission denied response.
Any help is appreciated.

Nah, don't. I have read it before, and it is probably on

Why do you personally need to write a device driver for the KX-P6100?
GhostScript supports the HP LaserJet IIP, and the KX-P6100 emulates the
HP LJ2P in PCL mode. If you are using, for instance, RedHat 5.2, you
only need to tell the printtool that the printer is an HP LJ2P, and
you're go to go.
You can learn which devices your current version of GhostScript
supports by executing 'gs -help'
Enjoy!

termio is obsolete. Use termios instead.

There is no termio man page, but there is a termios manpage.
Here's the contents of /usr/include/termio.h on my system:
--- termio.h ---
/* Compatible <termio.h> for old `struct termio' ioctl interface.
This is obsolete; use the POSIX.1 `struct termios' interface
defined in <termios.h> instead. */
#include <termios.h>

Subject: Printer Accounting
Date: Mon, 01 Mar 1999 15:34:56 +0800
Hi wizards!
In RedHat 5.1, I tried to setup a print queue with accounting
so that all users' printing will be logged with no. of pages
printed. However, the log file won't update itself!
I added the line
:af=/var/spool/lpd/lp/acct:\
in /etc/printcap file;
then touch the file 'acct' in /var/spool/lpd/lp folder,
then set the file with lp.lp ownership while the
folder is in root.daemon ownership, with 755 mode for both
file and folder.
Then I restart lpd daemon (also lpc with stop and start
option). Root user can then type
# pac
and recognize the file /var/spool/lpd/lp/acct
as I tried to edit this file thru vi and 'pac'
does read this file which means lpd should have
chosen this file as the accounting log file.
However, when I issue 'lpr' command by normal users
or root, the printing is fine, but the 'acct' file
doesn't update at all!!!
I'd read the 4.3 BSD Line Printer Spooler Manual
but still can't see the problem. Any other accounting
binaries I need to run, like sa? Did I miss some other config
in some files, like syslogd.conf?
Wd anyone pls tell me what's wrong with
my printcap config? I used the HP4/5/6 Laserjet filter
as provided by RedHat 5.1, any conflicts with af: line?
Pls help! Thank you very much in advance
Leo.

Yes. Gordon Chaffee (the kernel vfat/fat32 guy) distributes a
"fat32-enabled" FIPS from his ftp site. The patch was supposed to make
it into the main FIPS distribution; I assume it did. In any case
Chaffee's site has it:

Read the glibc2.1 FAQ:

segmentation faults.

autoconf abstracts from different systems and shouldn't need to check
especially for glibc.
But if you really like to check for glibc, look at <features.h>:
/* Major and minor version number of the GNU C library package. Use
these macros to test for features in specific releases. */
#define __GLIBC__ 2
#define __GLIBC_MINOR__ 1
