Synopsis:          New SysVinit package to fix hangs on serial console
Advisory ID:       RHBA-2001:085-02
Issue date:        2001-06-21
Updated on:        2001-06-22

1. Topic:

New SysVinit packages are available for Red Hat Linux 7.1; these packages
fix a problem where various things would fail on a serial console (such
as single user mode) when used with the Linux kernel version 2.4.3 or higher.

It is recommended that all users update to the fixed packages, especially
those that use a serial console.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - alpha, i386

init did not properly set the CREAD flag; with the 2.4.3 (and later) kernels,
this could cause applications to be unable to receive input from a serial

Thanks go to vhou khmer cc for providing the patch.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

42280 - Serial console and single user mode don't cooperate
