Hello,
A while back I sent a message saying that I had solved my problems with
Braille output by getting rid of a winmodem which was in serial port 3,
sharing an IRQ sith serial port 1, where my Braille Lite is connectedd.
This was a bit premature. After running kudzu and rebooting things were
much better, but something still interferes from time to time. I think the
Redhat 7.1 install program must have installed something for the modem
which is still trying to use IRQ 4. So I ran chkconfig --list to try to
spot the rogue process. The output is below. Which processes should I get
rid of?
Thanks.
John

What you are listing there are not processes. Those are references to 
scripts that will start different processes or daemons when switching to 
a particular run level.

In order to see processes run 'ps -ax' or a variant of that.

Unless you are using PPPOE or isdn then you might want to turn those off 
in run levels.

More usable information to troubleshoot your problem could be get with

cat /proc/devices
cat /proc/interrupts
cat /proc/ioports
procinfo

and of course dmesg that tells you what happened during boot.

Serial ports are normaly not messed up in Linux unless the BIOS has 
something to do with it. It is possible to swap or change parameters for 
serial port configuration under BIOS. Since you have winmodem it might be 
a good idea to configure whatever serial port you have problems with to 
use another (nondefault) IRQ. Interrupt lines 10, 11, and 15 are not used 
in all computers unless you have two hard drives and SCSI controller.

You can make changes to serial port configuration with command setserial.
In my old Pentium 120 with SCSI, 2 IDE drives, serial port for mouse, and 
X-10, and a modem I had to do that. Fortunately, the modem was able to 
work using IRQ 10.

Newer motherboards with PCI can use additional interrupts above 15, up to
31 I believe. That makes it easier to spread the hardware configuration
and accomodate all peripherals in the system.

Man I hate Pee Cee architecture!

Hi John, 
I hav'nt followed your emails  on the braille device, but here are
one or two things you can try.
1.  cat /etc/modules.conf and look
for some thing grabing the interrupt in question.
I read something about a winmodem.  You might find the module
for that modem are still configured in /etc/modules.conf.  
do dmesg | more and look for some thing related to your com ports.
You will see what the system think their interupts and io-base addresses 
are.
You can also look in /var/log/messages for messages produced
by the modules as they were loaded.
regards, Willem,
ps. did you receive catdoc ok?
