http://bugme.osdl.org/show_bug.cgi?id=982

Summary: cu -l /dev/ttyS0 got a signal hangup in 2.5 kernel
Kernel Version: 2.5.75
Status: NEW
Severity: normal
Owner: rmk@arm.linux.org.uk
Submitter: hien1@us.ibm.com
CC: sglass@us.ibm.com


Distribution: SuSE SLES8
Hardware Environment:NetVista 6579-A4U Pentium III - 866 MHz 256MB RAM
Software Environment:2.5.75 kernel
Problem Description: cu session fails to log into the other machine which is connected with a
null modem serial cable between serial ports.
It works fine in 2.4.19 4GB kernel

Steps to reproduce:
1. connecting two systems with a null modem serial cable between serial ports.
2. On one machine, do : cu -l /dev/ttyS0
On other system, have /sbin/agetty -L 9600 ttyS0 vt100 running.
and ttyS0 has been defined in /etc/securetty
3. cu session connected and showed you the login prompt.
4. Got a hangup signal and disconnected after typing "root" or any user ID.
It supposes to prompt you "password:" to let you type the password of the other machine
to login to that system.
