Re^2: I want to know exactly what comes through a socket

Can I see their hex values? Or something like that ;]
I see you use sprintf and ord, but that form of using is too complicated for my poor human mind ;) Could you enlighten me a bit, please?

The top snippet does display their hex values (embeded in a Perl-style hex character escape). `ord($1)` returns the character number of the character in $1. For a tab, it would return the number '9'. `sprintf("%02X", ord($1))` returns the hex character number of the character in $1. For a tab, it would return the string '09'. `sprintf("\\x{%02X}", ord($1))` returns the hex character escape for the character in $1. For a tab, it would return the string '\x{09}'.
