("Configuration") Tells PHost to send you the pconfig.src file within your utilx.dat next turn. You can also use the send config command instead of this friendly code.
A number of add-ons will react on this friendly code (by sending configuration messages), too.
In HOST, this friendly code causes HOST to send you the configuration as a set of sub-space messages. PHost's configuration is too large to fit in sub-space messages.
