2007/11/09! 03.56.29! E00549! Enq_pty! Tty.c! 119! PID (22597)! Operations ioctl (TCS
helo,
i got accessing system from putty.

a user has had System Telnet up (for hours at a time) and been running various commands from the CUI menu.(its just client application) The following message appears over and over again in the account log:
2007/11/09! 03.56.29! E00549! Enq_pty! Tty.c! 119! PID (22597)! Operations ioctl (TCSETAW) failed,
file 'tty - errno 5: Input / output error

This problem is still happening. While the problem can be resolved, at least temporarily, by restarting all services.but I need to find out why this is occurring. The results vary slightly, but basically the client applications become unable to connect to the system.

what to do
Regards,
Amit

alevt-date

ALEVT-DATE(1)							   Teletext time						     ALEVT-DATE(1)

NAME

       alevt-date - display/set time received via Teletext

SYNOPSIS

       alevt-date [options]

DESCRIPTION

       alevt-date displays the time received from a Teletext source.  It can be used to set the system time.  The date is not interpreted (not
       even transmitted on most channels).  So it allows only adjustment of +/-12 hours.  The default allowed adjustment is limited to +/-2 hours
       (use -delta to change).	Without the -set option it just displays the date in the format of the date(1) command.

OPTIONS

       A summary of options is included below.

       -set		 Set system time from time received via Teletext.

       -delta seconds	 Maximum allowed adjustment made to the system time.  The default is 7200 seconds (2 hours) and the maximum that may be
			 given is 12 hours.

       -format string	 Format string to used to print the time.  Look at strftime(3) for possible control sequences.

       -vbi device	 Use the given device name.  Default: /dev/vbi, /dev/vbi0, /dev/video0, /dev/dvb/adapter0/demux0 tried in this order.

       -timeout seconds  If the time can't be detected in seconds, the program is terminated with a SIGALRM.

       -progname name	 Specifies the program name if using the DVB interface.

       -pid pid 	 Specifies the teletext PID if using the DVB interface.

       --help		 Show summary of options.

       --version	 Show version of program.

       Before starting this program, you have to set the TV channel with another program like xawtv of set-tv.

       Note: This program does not set the battery backed up clock of your computer.  clock -w will do this.

       The -progname or -pid option specifies the program or teletext PID if using the DVB interface.

       If neither of these two options is used, alevt outputs informations about the currently accessible streams and uses the first of these PIDs
       as default. This output contains the PIDs and names that can be used as an input for the -progname or -pid option in the context of the
       currently chosen TV channel.

FILES

       /dev/vbi*

       /dev/dvb/adapter*/demux*

SEE ALSO

       alevt(1x), alevt-cap(1), strftime(3), date(1), clock(8).

BUGS

       This program is just a toy.  The time transmitted by the TV stations is more than inaccurate.  Some are within a few seconds of your local
       time reference but others are more then 15 minutes off.	You've been warned.  (And don't assume the pkt8/30 time is better.  It's even
       worse.)

       No bug reports to <froese@gmx.de> *g*.
