Thanks Michal, but according to those pages...

"When Asterisk starts an AGI script, it feeds the channel variables to
the script on standard input. "
www.voip-info.org/wiki/view/Asterisk+AGI

"All communication with the AGI occurs over STDIN and STDOUT; [...]
When your program starts, Asterisk will stream a number of variables
to it, which it's in your interest to capture. "
www.voip-info.org/wiki/view/Asterisk+AGI+php

... the server does end each line with a CRL/LF, ending with an empty
CR/LF line when done, so I can't figure out why the while loop never
ends.
