</question>
<answer>

<para>Many &kde; users report problems using &kppp;.  But before you
complain about &kppp;, make sure you have already checked the
following:</para>

<itemizedlist>
<listitem><para>Can you dialup to your <acronym>ISP</acronym> without using &kppp;?  If you cannot, then perhaps &kppp; is not the culprit after
all.</para></listitem>
<listitem><para>Have you gone through the &kppp; documentation at
least three times and followed its instructions and trouble-shooting
suggestions?</para></listitem>
</itemizedlist>
<para>The &kppp; documentation can be accessed through the 
<application>&kde; Help Center</application>.
 Last, but not least, the &kppp; homepage is at <ulink
 url="http://ktown.kde.org/~kppp/">http://ktown.kde.org/~kppp/</ulink>.</para>
<para>Now, if you still encounter problems, here's what might help you
solve them:</para>
<variablelist>
<varlistentry><term>How do I change the &MTU; setting in &kppp;?</term>
<listitem><para>Open up the &kppp; dialog box and select
<guibutton>Setup</guibutton>.  Choose an existing account and click
<guibutton>Edit</guibutton>, or <guibutton>New</guibutton> to create a
new dialup account.  Select the <guilabel>Dial</guilabel> tab and
click <guibutton>Arguments</guibutton>.  Type what you want to change
in the Argument textbox (&eg; <userinput>mtu 296</userinput>) and
click <guibutton>Add</guibutton>.  When you are satisfied, click
<guibutton>Close</guibutton>.</para>
<para>To check whether the options <quote>took</quote>, do one of the following:</para>
<itemizedlist>
<listitem>
<para>In a terminal window, run
<userinput><command>/sbin/ifconfig</command> ppp0</userinput> and look
at the reported &MTU; in the output.  It should match your
request.</para>
</listitem>
<listitem><para>Add <option>debug</option> and <option>kdebug</option>
(each on a separate line) to your
<filename>/etc/ppp/options</filename> file and restart your
&PPP; session.  You will find debugging messages in
<filename>/var/log/messages</filename>, including &MRU; and &MTU;
settings.</para></listitem>
</itemizedlist>
<para>If you want, the &MRU; and &MTU; settings can be added to the
<filename>options</filename> file, one complete setting per line, no
quotes or dashes.</para></listitem>
</varlistentry>
<varlistentry>
<term>&kppp; connects at a slower speed than
normal.</term>
<listitem><para>The following might do the trick:</para>
<itemizedlist>
<listitem><para>Try executing <command>setserial
spd_hi</command>.</para></listitem>
<listitem><para>The default &MTU; value is 1500,
which maybe too large 
for a dialup connection.  Try changing it to a smaller value like
<userinput>296</userinput>
or <userinput>576</userinput>.</para></listitem>
<listitem><para>Check in your <filename
class="directory">$<envar>HOME</envar>/.kde/share/config</filename> for the 
<filename>kppprc</filename>.  Ensure the correct modem speed is
actually defined there.</para></listitem>

<para>&konsole;</para>
</question>
<answer>
<variablelist>

<varlistentry>
<term>How do I page-up or page-down?</term>
<listitem><para>Use <keycombo action="simul">
&Shift;<keycap>Page Up</keycap></keycombo>
and <keycombo action="simul">&Shift;<keycap>Pg
Dn</keycap></keycombo>.
</para></listitem>
</varlistentry>

<varlistentry>
<term>How do I perform a simple <quote>copy</quote> from &konsole; to
anything else?</term>
<listitem><para>When I do a <command>ls</command>, first I select with
the mouse the desired text, press 
<keycombo action="simul">&Ctrl;<keycap>C</keycap></keycombo>,
then I make the target application active, point the mouse to the
relevant part and press <keycombo
action="simul">&Ctrl;<keycap>V</keycap></keycombo>.
Alternatively, highlight the text by dragging with the &LMB; down and
paste by clicking with the &MMB; (or both buttons if you are using a
2 button mouse with 3 button emulation).

<varlistentry>
<term>Why can't &konsole; find the <quote>9x15</quote> and the 2
<quote>console</quote> bitmap fonts installed with &kde;?</term>
<listitem>

<para><application>FontConfig</application> must find the three fonts
installed in: <filename
class="directory">$<envar>KDEDIR</envar>/share/fonts</filename>. 
 If
the &kde; install does not install these fonts in a directory that
already exists (&eg; <filename
class="directory">/usr/share/fonts</filename>) then you must add this
directory to the configuration file <filename
class="directory">/etc/fonts/local.conf</filename>.  This should be
the first line after <quote>&lt;fontconfig&gt;</quote>.  For example:
<programlisting>
&lt;fontconfig&gt;
&lt;dir&gt;/usr/kde3/share/fonts&lt;/dir&gt;
&lt;/fontconfig&gt;
</programlisting>
After adding the directory, run (as root):
<userinput><command>fc-cache</command> -v</userinput> and check that
it found the directory.</para>
