There are a few different kinds of winmodems -- HSP (host signal
processing), which only have a D-A and rely on the host to do the DSP,
and HCF (controller-free), which have a data pump and rely on the host
for modem control. So both kinds of modems exist.

There is no (ix86) checksum.c file in the 2.2 kernel series. It must
be left over from some old kernel source. Delete it.

Okay, attached below is a stripped down version of what I'm trying to
do. This is just a minimal test to see if I can talk to a PCI board
at all.. (it's a board that uses AMCC's S9533, and I'm trying to read
the control register... but just getting 0xff's for every byte that I
read... (meaning a 0xffffffff for 32-bit reads)).
I've tried ioremap(), ioremap_nocache() cause it's non-prefetchable
memory, and __ioremap() with other options I thought might be
helpful... I've tried ioremap(virt_to_bus(addr)) as well. But
nothing is getting anything but FF's.
Some kind soul please help me out?
Thank you kindly,
Danny Sung
PS: I am using RH60, kernel 2.2.5, btw. Oh and it does indeed find
the board's configuration registers and all... I just took the
verification code out focus on the problem.

I had this problem too - although 16MB was as far as I could see. I was
advised to investigate the "cruft" mount option for the iso9660
filesystem, but didn't get around to it as my box is dual-boot, and I
used Win95 to pull it off the CD.

Subject: shared memory segment
Date: Wed, 23 Jun 1999 11:21:49 -0400
hi:
i was trying to hack a little bit of ipc and mm code so that i could
create a shared memory segment that point to a specified real address. i
created a segment type called MY_SEG and if that flag is passed to
shmget i put in a specific key from shmget itself so now all the shmget
requests with MY_SEG flag point to the same physical page regardless of
the key passed to shmget because i am changing that key to a specific
key from within shmget itself.
after doing this i want to be able to point the shared segment to a
specific hardware address. for instance all the shmget with MY_SEG
should eventually allow me to access address starting lets say
0x50800000.
does anyone have relevant experience in tweaking this kind of things?
thanks in advance.

Subject: localhost call fails on Redhat 6.0 when built on SUSE 5.3
Date: 23 Jun 1999 14:30:54 GMT
Hello all,
I current have a program which utilizes the localhost call to determine
the correct time.
When I build my program on SUSE 5.3 (statically - libc5) and run this
program
on Redhat 6.0, the localhost call fails.
In addition, when the program is run on Redhat 5.2, SUSE 6.0, Caldera,
etc. it works fine.
When I build the program on Redhat 5.2, and run it on Redhat 6.0, it also
runs fine.
It seems that there is a issue with libc5 on SUSE (statically linked) when
run on Redhat 6.0.
What is the issue here?
I need to build on SUSE 5.3 and have my program run on all other OS's.
Please help. What can I do to accomplish this.
I have attached my code snippet below.
Thanks,
Mike
#include <stdio.h>
#include <time.h>
main(){
time_t current_time;
struct tm *tblock;
char time_string[128];
tzset();
/* gets time of day */
current_time = time(0);
printf("current_time = %d\n",current_time);
/* converts date/time to a structure */
tblock = localtime(¤t_time);
strftime(time_string, 127, "%m/%d/%y,%H:%M:%S", tblock);
printf("time_string = %s\n",time_string);
printf("tzname = %s\n",tzname[daylight]);
printf("daylight = %d\n",daylight);
printf("timezone = %d\n",timezone);

So let's change that! I bet if we can help the modem manufacturers
sell an extra 1000 modems a month they'd be happy to help us write
the drivers. I ain't no salesman, but I can deal with modem tones
no problem!
The winmodem is just a digitizer that does DMA into a buffer. The
processor has to convert the audio bits to multiple tone data, and
then to data bits. It's straight forward data manipulation. There
is no reason we can't write a driver for any winmodem.
Who wants to go where no one has gone before?

Since all the 'big' databases (Sybase, DB2, Oracle,...) have more or
less free versions for Linux, I think the high-end market about filled
up.
What you should go for is a front-end to these DBs, to make building
applications easier.
Or you could try for something similar to what Windows users have,
Fics <http://www.kvamdata.no>, Lotus Approach or any of the competing
products: A lightweight database, which also can connect to a 'real'
database (the big ones mentioned above).
