From the /etc/inittab file (assuming console or directly plugged terminal) comment out the line has the terminal tty.
For example, if you wanted the console not to be allowed, change the word 'respawn' to 'off'
cons:123456:respawn:/usr/sbin/getty console console

You could also stop users logging in by adding an exit statement to their .profile file.

Hi sunny,
Can you tell us how the terminal is connected to the server. Is it through directly connected through serial port. If that is the case then /etc/inittab is the file..

Hi,
Actually, My terminal is connected to the appliction server through terminal server. keyboard and a card reader mechine are connect to the terminal. when the terminal call a c program to read information from the card reader, if I press any key, the program will end with a error:program is terminated by ctrl_c. so I wish if I can disable the keyboard
, the program will not exit.

Thx
Sunny

Hi Sunny,

how about simple commands like:

to STOP: stty -g > ~/tty-set; stty -isig -brkint -cread

to CONTINUE: stty $(cat ~/tty-set)

That should work fine ;-)

FWIW,
