<H3>Overview</H3>
<P>The Target Selection Dialog allows users to specify the debug target,
the interface used to connect to the target, and some useful run
options.</P>

<H3><A NAME="select">Selecting a Target</A></H3>
Selecting a target involves choosing a target for debugging and setting connection
interface options for the target. 

<P>Common targets include: "exec" for native debuggers, "remote" for establishing
a connection to a target board via a serial line, "remotetcp" for TCP connections,
and "sim" for connections to the simulator. There may be more depending on the
configuration of the debugger being used.</P>

<P>In general, "remote" targets are always serial connections which require the user
to specify the serial port and baud rate to be used for the connection and
"remotetcp" targets are always TCP connections which require specifying the hostname
and port number of the machine to which to connect. Depending upon configuration,
there may be numerous serial- and TCP-based connections. These always follow the
naming convention <I>target</I> and <I>target</I>tcp.</P>

<P>To <A NAME="select_tar"> select a target</A>, choose one of the available targets
from the dropdown menu in the Connection Frame. Then <A NAME="#select_int">specify
the interface options</A> for this target: selecting the baudrate and serial port
from the dropdown menus (serial targets only) or entering the hostname and port number
(TCP targets only).</P>

<H3><A NAME="options">Run Options</A></H3>
Three run options which may be selected include:
<DL>
    <DT><A NAME="options_run_until_main">Run until 'main'
        <DD>Sets a breakpoint at main(). This has no effect when using
            GDB in tracing mode.
    <DT><A NAME="options_bp_at_exit">Set breakpoint at 'exit'
        <DD>Sets a breakpoint at exit(). This has no effect when using
            GDB in tracing mode.
    <DT><A NAME="options_download_dialog">Display Download Dialog
        <DD>Displays a dialog showing the progress of the download to
            the target section by section. This has no effect when using
            GDB in tracing mode.
    <DT><A NAME="options_compare_to_remote_executable">
        Compare to remote executable</A>
        <DD>When attaching to a tracing target, compare the host's and target's
            executable by computing the checksum of each loadable section.
