PHP4 listening host:port

I'm running my test server on Windows XP SP3 and have been successfully
running PHP 5 for some time using:

    php-cgi.exe -b 127.0.0.1:10000

My live server is running on PHP 4 and that gives an incompatibility risk in
problem solving. So I've removed PHP 5 on my test server and have installed
PHP 4.4.9 but I can't find how I set host and port in php.

Running php -v has confirmed that this is the cgi-fcgi version.

I'm sure it's simple but I'm being driven nuts.

TIA,

John
