Hi Jonathan,
Thank you for your reply....
Basically, I'm trying to spend some time now in order that I might be
lazy later :-)
Right now, I do:
# insmod mymodule.ko; dmesg | tail; # look at printk messages
# rmmod mymodule
(go fix mymodule and try again)
I would like to do
# setconsole mypty
(once, when I log in)
(repeatedly, as I debug my module)
# insmod mymodule.ko
(see printk messages spewing back at me -- I happen to be logged in via ssh)
# rmmod mymodule
(go fix mymodule and try again)
Look at all of those pesky "dmesg | tail" I don't have to type anymore.
As I said, I'm just trying to be lazy here, and thought I recalled an
ioctl for redirecting the console (such as is done with a Konsole
window in KDE, and I've read is done with screen as well).
I figured I couldn't be the first person to be that lazy, but I guess
I'm asking the wrong group :-)
