You need a termination point. In the case of ReadString it is the line
terminator. For an arbitrary read it is either a length or EOF - or you can
read until the underlying socket has no more data but this is generally useless
unless you are doing higher level buffering and protocol parsing. This latter
mode is almost never needed in Go due to synchronous nature.
