In addition, 60<span class="sc">gdb</span> comes with a generic serial protocol (specific to <span class="sc">gdb</span>, 61but not specific to any particular target system) which you can use if you 62write the remote stubs—the code that runs on the remote system to 63communicate with <span class="sc">gdb</span>. 64 65 <p>Other remote targets may be available in your 66configuration of <span class="sc">gdb</span>; use <code>help target</code> to list them. 67 68<ul class="menu"> 69<li><a accesskey="1" href="Connecting.html#Connecting">Connecting</a>: Connecting to a remote target 70<li><a accesskey="2" href="File-Transfer.html#File-Transfer">File Transfer</a>: Sending files to a remote system 71<li><a accesskey="3" href="Server.html#Server">Server</a>: Using the gdbserver program 72<li><a accesskey="4" href="Remote-Configuration.html#Remote-Configuration">Remote Configuration</a>: Remote configuration 73<li><a accesskey="5" href="Remote-Stub.html#Remote-Stub">Remote Stub</a>: Implementing a remote stub 74</ul> 75 76 </body></html> 77 78
