Yes, "0my message here\n" really works. It gets printed on the remote
terminal as well. However, it does have a side effect. The speaker beeps
with each line of output and inserts another line "Message from
syslog@mymachine at Thu Apr 5 01:04:30 2001 ..." between each line of
output. It looks (and sounds) like one of those broadcast messages that
operators send to users before shutting down.
Nevertheless, it does work, and I might just disable my speaker. I have
not yet tried Eric Peterson's suggestion (man klogd(8)). I am indeed
grateful for all the responses on this question.

I borrowed a piece of code a while back and here is one thing that I saw.
printk("0my message here\n");
I changed it to
rtl_printf("0my message here\n:);
and in both cases the message was broadcast to all open windows and also
logged to be viewed by dmesg.
I do not know how this performs when remotely logged in.
I don't know why this works this way but it could be useful.

Hi Siva,
Typing dmesg at the remote terminal does allow viewing of the kernel ring
buffer on the other machine. It does what I want, although it would be
nice if you didn't have to type dmesg all the time. Probably the only
other way to get the print messages out of the rtl module is through a
fifo?
Thanks very much
Ollie

Hi,
if my understanding is correct, rtl_printf messages go directly
to
the console of the system. to view these messages, you can use dmesg so
that all the logged messages can be seen from the remote terminal.

siva

Subject: [rtl] print_rtl during remote login
When I operate my rtlinux machine remotely using rlogin from another
machine, the printf_rtl output from within my program goes to
the screen of
the rtlinux machine instead of to the remote machine. This behavior
applies not just to my output but also to other rtl messages such as
"RTLinux Extensions Loaded (http://www.fsmlabs.com/)".
But regular operating system messages, including the gdb
debugger messages,
do go over to the remote machine as expected.
Is there a mechanism for redirecting the standard output?
This seems like an important capability that probably has an
easy answer.
Thanks
Ollie
