I'm not at all sure what you're asking.
You mention token ring. I guess that means
you have two or more systems networked
with token ring network adaptors?
I also assume you're running TCP/IP?
I'm not sure what you mean by a "pipe" with
regard to token ring. As far as passing messages,
assuming you're asking about network programming,
you shoudl check out the sockets library man
pages (i.e. sendmsg, recvmsg, etc, etc...)

NAME
dmesg - print or control the kernel ring buffer
SYNOPSIS
dmesg [-c] [-r] [-n level] [-s bufsize]
DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.
The program helps users to print out their bootup messages. Instead of copying the messages by hand, the user need only:
dmesg > boot.messages
and mail the boot.messages file to whoever can debug their problem.
OPTIONS
-c Clear the ring buffer contents after printing.
-r Print the raw message buffer, i.e., don't strip the log level prefixes.
-s bufsize
Use a buffer of size bufsize to query the kernel ring buffer. This is 16392 by default. (The default kernel syslog buffer size was
4096 at first, 8192 since 1.3.54, 16384 since 2.1.113.) If you have set the kernel buffer to be larger than the default then this
option can be used to view the entire buffer.
-n level
Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, except panic messages,
from appearing on the console. All levels of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control
exactly where kernel messages appear. When the -n option is used, dmesg will not print or clear the kernel ring buffer.
When both options are used, only the last option on the command line will have an effect.
SEE ALSO
syslogd(8)
AVAILABILITY
The dmesg command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
