+        dialing-up a server computer from a client computer through a
+        Modem attached to the telephone line. In this infrastructure,
+        dial-up connections are always established from the client
+        computer to the server computer and never the other way
+        around.  The main purpose of a client computer to establish a

+        In order for the server computer to answer telephone calls, it
+        is required to install a Modem device in it (see <xref
+        linkend="server-install-hardware" />). Once the Modem device
+        has been installed, you need to install and configure both
+        <application>mgetty</application> and
+        <application>pppd</application> programs.  The
+        <application>mgetty</application> program must be run by
+        <systemitem class="daemon">init</systemitem> daemon in order
+        to take control over the Modem device. By default, inside
+        &TCD; (release 5.5), mgetty isn't configured to start with
+        <systemitem class="daemon">init</systemitem> daemon so you
+        need to do it yourself (see ...). Later, for attending
+        connection requests, you need to configure mgetty to use the
+        <application>pppd</application> program, so the Point-to-Point
+        Protocol (PPP) can be talked and IP packages can be
+        interchanged between the client computer and the server
+        computer. Later, you need to configure
