a terminal that is known by ELinks and have a built-in configuration (see below
for a list), it might be required that you do a little configuring of how your
terminal should be handled. The easiest way to do this is by using the Terminal
Options dialog located in the Setup submenu of the Main menu.</p><p>It is possible to have configurations for multiple terminals as long as the TERM
environment variable — used to distinguish terminals from one another — is set
to something different for each terminal. So be sure to set TERM to different
values for two terminals that cannot share the same configuration. For example,
always setting TERM to xterm-color can lead to problems if you run ELinks under
the Linux console. This is because the Linux console does not support
underlining and ELinks will not know that underlined characters will have to be
color highlighted so they stand out.</p><p>In short, ELinks does not use termcap or terminfo. ELinks uses $TERM, but only
to distinguish between terminals in its own configuration. That is, you need
only configure your terminal within ELinks: Go to the Setup menu and select
Terminal Options. If $TERM is set to <span class="emphasis"><em>screen</em></span> when you configure ELinks'
terminal settings, ELinks will remember to use those settings when $TERM is
<span class="emphasis"><em>screen</em></span>.</p><div class="section" title="Options"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp6640384"></a>Options</h2></div></div></div><p>Apart from the last charset option configurable through the Setup -> Character
Set submenu in the Main menu, the rest can be configured using the Terminal
Options dialog.</p><div class="section" title="Terminal type"><div class="titlepage"><div><div><h3 class="title"><a name="idp6641856"></a>Terminal type</h3></div></div></div><p>It maps roughly to the terminal type, such as Linux console, XTerm, VT100 etc.
It matters mostly when drawing frames and borders around dialog windows. As
already mentioned, it also turns on certain features which try to compensate for
“missing” terminal capabilities when drawing. Special highlighting of
underlined text if underlining is not supported is one such thing.</p><div class="informaltable"><table border="1"><colgroup><col width="130pt" align="left"><col width="293pt" align="left"></colgroup><thead><tr><th align="left">

particularly useful when we have a block cursor, so that text colors are
displayed correctly. If you are using a screen reader you do not want to enable
this since the cursor is strategically positioned near relevant text of selected
