+
+<p> "I use Foomatic-9000 modem. In my modem, BusyBox v1.23.4 is installed.
+    I can reach my modem's Telnet interface and I can reach shell prompt.
+    I want to change configuration, and add some tools. Can I enable FTP?
+    SCP? If I edit a file on the device, I can't save it, I get
+    'filesyste is read only' error. How can I save a changed file?"
+</p>
+
+<p> Questions like the example above is a sign that the person asking it
+    does not fully understand what BusyBox is. BusyBox is not a complete
+    solution for running modems, or wireless access points, etc.
+    BusyBox is only a set of programs. Even though it is a fairly
+    comprehensive set of programs needed to run a Linux system, these
+    programs per se can not "run a modem".
+</p>
+
+<p> In order to make BusyBox-based system useful, developers of this system
+    add their own parts. At the very least, there are some shell scripts
+    and configuration files, which control which tools are to be run,
+    when, and how.
+    Often, there are also some web pages and CGI scripts (in order
+    to implement web-based configuration). Also, often developers add
+    other tools beside Linux kernel and BusyBox.
+</p>
+
+<p> Since these scripts, configuration files and other tools are
+    custom-designed for a specific device, BusyBox mailing list is usually
+    a wrong place to ask about inner workings of such a device.
+    You are better off googling for a forum where users of this particular
+    device discuss their findings about inner workings of the device,
+    and joining it.
