Re: Ncat -w -i options bugfixing

[Carlos Manso <carlos.manso () gmail com>]

Hello again,

Yes you are right, -w option is fine, but, if I'm not wrong, -i option
actually quits on listen mode while waiting for a connection to be
established, and this shouldn't be happening.
And also, the -i explanation I copied before (from the webpage) should be
changed to reflect it also works on connect mode.

Thanks,

Carlos Manso.
