I have a few SPARC machines here that I often run with a serial
console rather than a monitor. The problem is (and this is with
all RH 6.x for SPARC, including the lattest beta 6.1.92) that
neither ctrl-c nor ctrl-d work by default. If you hit them,
they're almost registered as normal keystrokes and do not function
normally. The problem can be traced to this line in /etc/inittab:
co:2345:respawn:/sbin/getty console DT9600 vt100
The problem is that the getty mistreats /dev/console on SPARCs
somehow. This is easily fixed in one of two ways:
a) Change that line to use use ttyS0 device rather than the console
device. If you change it to
co:2345:respawn:/sbin/getty ttyS0 DT9600 vt100
then all will be well (and you'll of course need to add "ttyS0" to
the /etc/securetty file).
b) Change the getty in use. Debian uses "agetty" with util-linux,
which doesn't have show this problem. A correct /etc/inittab line is
co:2345:respawn:/sbin/agetty -L console 9600 vt100
if agetty is installed on the system.
Redhat can fix this by either packaging and defaulting to a different
getty, or defaulting to /dev/ttyS0 instead of /dev/console for the
This bug is reproducable easily. If anyone would like to verify it
for themselves using my machine, email me or talk to Matt Wilson
about contacting me.

This problem persists in RedHat 6.2 and 7.0.
Bug 9948 is being closed with Red Hat Linux 7.0 and 6.2 coming to end of life,
and Red Hat no longer pursueing a Sparc port. Please look at
