Maybe suffering from buffering ? Try to set `$\|=1` . Just a guess, you didn't really provide much information... Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :)}	[reply] [d/l]

I tried this in the program text. I also tried this in debug mode. It didn't really do anything.	[reply]

Did you try 'reset'? And maybe post the output of 'stty -a' (not sure if that's a Perl's issue, though)	[reply]

Re: My Key Strokes are not echoed when typing in debug mode. by Anonymous Monk on Nov 18, 2014 at 00:33 UTC
Your stty settings look fine. perldebug has this: "ornaments" Affects screen appearance of the command line (see Term::ReadLine). There is currently no way to disable these, which can render some output illegible on some displays, or with some pagers. This is considered a bug. So maybe you encountered this bug. The doc says something about readline, so maybe try `$ PERLDB_OPTS=Readline=0 perl -d myprogram.pl` [download]	[reply] [d/l]

Yeah, That didn't work either... I thank you for tring. Maybe there is nothing I can do at this time. Thanks again, Mike	[reply]
