</question>
<answer>

<para>Many &tde; users report problems using &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
and followed the instructions and troubleshooting
suggestions?</para></listitem>
</itemizedlist>
<para>The <ulink url="help:/kppp">&kppp; handbook</ulink> is available through the
<application>&tde; Help Center</application>.</para>
<para>If you still encounter problems, then the following might help:</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>/.trinity/share/config</filename> for the
<filename>kppprc</filename>. Ensure the correct modem speed is
actually defined there.</para></listitem>

<variablelist>

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

<varlistentry>
<term>How do I copy text from &konsole; to
anything else?</term>
<listitem><para>Use the mouse to select the desired text. From the
<guimenu>Edit</guimenu> menu, select <guimenuitem>Copy</guimenuitem>, or press
<keycombo action="simul">&Ctrl;&Shift;<keycap>C</keycap></keycombo>. This places
the text in the &tde; clipboard, &klipper;. Next select
the target application, place the mouse pointer to the
desired location and press <keycombo
action="simul">&Ctrl;<keycap>V</keycap></keycombo>.
Alternately, 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).
</para><note><para>Note that the copying and pasting keyboard shortcuts use the
<keycap>&Shift;</keycap> key. That is because in traditional Unix terminals,
<keycombo action="simul">&Ctrl;<keycap>C</keycap></keycombo> is used to break or stop
a process from running.</para></note></listitem>

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

<para><application>FontConfig</application> must find the three fonts
installed in: <filename
class="directory">$<envar>TDEDIR</envar>/share/fonts</filename>.
 If
the &tde; 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/trinity/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>
