How do I UNsuppress output on the terminal?

[Gary Schafer]

I'm running Gnu Octave 6.1.0 on Windows 10. I'm trying to parse out a data file. When I attempted 
to see if some of the data was ASCII, I put it into a "char" statement. After that, all 
of the output on the terminal is suppressed. However, I need that output. Is there something I did 
with the "char" command that may have suppressed the output? It's quite possible that any 
of the possible ASCII values, from 0 - 255, when into that statement. I've tried re-entering the 
command (hoping it would toggle the terminal output back on), but it didn't work.

Thanks,

Gary
