Er, what did you think the implication of "$line" was?
It will not go on until it receives characters terminated by \n or gets
an eof. Properly-behaved servers should be sending CRLF-terminated lines.

Take a look on CPAN for some of the modules for simplifying client/server
writing. Especially if your server is speaking a standard protocol; there
may already be a module for receiving it.
