Hi. Ta. It does work (in CMD mode). I had to add a "\n" to avoid the buffering of characters. Some console output follows (involving this change). 

C:\u\Perl_Eclipse_IDE\OBD2_control>
C:\u\Perl_Eclipse_IDE\OBD2_control>perl Note_02_NonBlockingSTDIN.pl
start
finish
...........Get key K

C:\u\Perl_Eclipse_IDE\OBD2_control>
C:\u\Perl_Eclipse_IDE\OBD2_control>
C:\u\Perl_Eclipse_IDE\OBD2_control>perl Note_02_NonBlockingSTDIN.pl
start
finish
.

Get key N

But I find it dis-appointing to lose the convenience of running from the IDE. Are there other IDEs that would accommodate ?

Regards JC....
