+ <title>soundmodem</title>
+ <para>
+ <application>soundmodem</application> provides an AX.25 interface
+ through a sound card device, eliminating the need for a TNC.
+ </para>
+ <para>
+ Before it can be used, <application>soundmodem</application> must
+ be configured by issuing the command:
+ <command>soundmodemconfig&</command>. This will launch the
+ configuration dialog.
+ </para>
+ <para>
+ Multiple configurations can be configured, the first step is to
+ start a new configuration:
+ <figure float="0"><title>soundmodemconfig</title>
+ <mediaobject>
+ <imageobject>
+ <imagedata scale="99" scalefit="1"
+ fileref="images/packet-soundmodem/soundmodem1.png"

+ </imageobject>
+ <textobject>
+ <para>
+ soundmodemconfig
+ </para>
+ </textobject>
+ </mediaobject>
+ </figure>
+ </para>
+ <para>
+ This will open a dialog requesting a name for the configuration:
+ <figure float="0"><title>Naming the configuration</title>
+ <mediaobject>

+ <para>
+ soundmodemconfig
+ </para>
+ </textobject>
+ </mediaobject>
+ </figure>
+ </para>
+ <para>
+ Enter the appropriate data for your sound card. The lower part
+ of the dialog is only applicable if <package>hamlib</package> is
+ to be used. The <guilabel>Channel Access</guilabel> tab
+ contains a few TNC parameters and generally the defaults should
+ be used until more experience is gained with the particular
+ channel:

+ <para>
+ After creating the configuration, it is now necessary to create a
+ new channel:

+ </para>
+ </textobject>
+ </mediaobject>
+ </figure>
+ </para>
+ <para>
+ The channel contains specifics about the modulation as well as
+ identification. For the modulator, the values shown below are
+ typical for VHF packet:

+ <para>
+ The demodulator will typically be set to the same values as the
+ modulator:

+ </figure>
+ </para>
+ <para>
+ the <guilabel>Packet I/O</guilabel> contains identification
+ specific to your station. The <guilabel>Interface Name</guilabel>
+ must match the name of port in
+ <filename>/etc/ax25/axports</filename> (<xref linkend="axports2" />)
+ if the <package>ax25-apps</package>((<xref
+ linkend="packet-ax25-apps" />) is to work properly. Similarly,
+ the <guilabel>Callsign</guilabel>, which should contain your
+ station's SSID must also match the value in
+ <filename>axports</filename>. The <guilabel>IP Address</guilabel>
+ should be the address assigned by your local AMPRnet coordinator.
+ The remaining fields have their typical meaning.

+ <para>
+ You must also set up <filename>/etc/ax25/axports</filename> to

+ You may now use the <application>axlisten</application> and
+ <application>axcall</application> applications described in <xref
+ linkend="packet-ax25-apps" />. If you have IP resources
+ available, you may also use ordinary network applications.
+ <application>soundmodemconfig</application> provides basic routes,
+ but depending on your local environment, you may wish to add
+ additional routes.
