Unrecognizable charactor display

Hi all,

  Happy New Year.

  I used the cat command to view the data file including some nondisplayable character, I keyed in characters in the command line after execution completed, I saw unrecognizable charactors displayed. 

  I would be very appreciated for your suggestion on how to solve it.     

regards,

not sure what your question is.

btw, ‘cat’ is probably not a good choice to view a binary data file.

I think his question is how to reset the terminal to return display to normal. Somehow the terminal must receive some escape code that switch mode or something. I know there is a reset code, but since I never remember it when it happen to me I close the terminal and open a new one ;-)
