<refsect1 id='description'><title>DESCRIPTION</title>

<para>The <command>morse</command> program is a Morse-code trainer
intended to help aspiring radio hams pass the 5-word-per-minute
Element 1 test.  It can take test text from a text file on standard
input, or test words from its command-line arguments, or generate
random text (-r) or play back what you type (-i).</para>

<para>A helper program, <command>QSO</command>, generates plausible
QSOs that can be fed to the standard input of <command>morse</command>.</para>

<para>Here is the basic International Morse codest that the program
will train you in:</para>

<screen>
        A  .-          N  -.          1  .----       .  .-.-.-
        B  -...        O  ---         2  ..---       ,  --..--

        E  .           R  .-.         5  .....       -  -....-
        F  ..-.        S  ...         6  -....
        G  --.         T  -           7  --...
        H  ....        U  ..-         8  ---..
        I  ..          V  ...-        9  ----.

        M  --          Z  --..        =  -...-
</screen>

<para>The following characters are included if one uses the -B option:</para>

<screen>
        )  -.--.-      "  .-..-.      _  ..--.-
        '  .----.      :  ---...      ;  -.-.-.
        $  ...-..-     !  -.-.--      @  .--.-.
</screen>

<para>The following procedural signals (prosigns) are also included if
one uses -B:</para>

<screen>
&lt;AR&gt;    "+" over, end of message
&lt;AS&gt;    "*" please stand by (&lt;AS&gt; 5  Wait 5 Minutes) (".-...")
&lt;BT&gt;    "=" (double dash) pause, break for text
CL          going off the air (clear)
CQ          calling any station
K           go, invite any station to transmit
&lt;KN&gt;    "(" go only, invite a specific station to transmit
R           all received OK
&lt;SK&gt;    "%" end of contact (sent before call) ("...-.-", known also as &lt;VA&gt;)
</screen>

<para>The following less-used prosigns are included if one
uses the -S option:</para>

<screen>
&lt;AA&gt;    "^" new line (".-.-", the same as :a, ae)
&lt;BK&gt;    "#" invite receiving station to transmit ("-...-.-")
&lt;KA&gt;    "&amp;" attention ("-.-.-")
&lt;SN&gt;    "~" understood ("...-.")
</screen>

<para>The following characters are included if one uses the -A option:</para>

<screen>
        :a  .-.-   (also for ae, the same as &lt;AA&gt;)
        `a  .--.-  (also oa, danish a with ring over it)
        ch  ----   (bar-ch ?, bar-h ?, ISO 8859-1 code 199 and 231 ?)
        -d  ..--.  (eth, overstrike d with -, ISO 8859-1 code 208 and 240)
        `e  ..-..
        ~n  --.--
        :o  ---.   (also for oe)
        :u  ..--   (also for ue)
        ]p  .--..  (thorn, overstrike ] with p, ISO 8859-1 code 222 and 254)
        paragraph  .-.-..  (ISO 8859-1 code 167 ?)
</screen>

<para>For the raw beginner trying to learn morse code, we recommend
the following sequence:</para>

<procedure>
<step>
<para>Start learning the alphabet:</para>
<programlisting>
morse -r -s -T -d -w 5 -F 15 -p 5 -E -10
</programlisting>
</step>
<step>
<para>Then drill drill drill:</para>
<programlisting>
morse -r -s -T -d -w 5 -F 15 -p 5 -E 0
</programlisting>
</step>
<step>
<para>Real-time drill, with hints if you really need it:</para>
<programlisting>
morse -r -T -d -w 5 -F 15 -M 2 -E 4
</programlisting>
</step>
<step>
<para>Simulated test:</para>
<programlisting>
QSO | morse -e -T -d -w 5 -F 15
</programlisting>
</step>
<step>
<para>The dreaded random-letter test:</para>
<programlisting>
morse -r -T -d -w 5 -F 15
</programlisting>
</step>
<step>
<para>Finally try for greater and greater speed:</para>
<programlisting>
morse -r -T -d -w 13 -F 24
</programlisting>
</step>
</procedure>
