A serial cable is connected between the host computer and the development board, data is then transferred between the host computer and the development board via a terminal program. The STAMP board has a DB9 serial connector for this purpose, connectors on other development hardware may vary. For more information consult the documentation for your particular development hardware.</p><p>To get started with U-Boot and uClinux a terminal program and a serial connection to the development board are required as U-Boot and uClinux both use this serial link for standard input and output. There are several terminal programs available for a number of platforms. Two common terminal programs, one for Windows and one for Linux, and the methods used to configure them for use with a STAMP board running U-Boot / uClinux are described below. Before preforming the procedures described below a serial cable should be connected between the host computer and the target system.</p></div><!-- SECTION [1-1287] --><h2><a name="linux_packages" id="linux_packages">Linux Packages</a></h2><div class="level2"><p></p><p>The two main GNU/Linux communication programs are <code>kermit</code> and <code>minicom</code>. Before you can run either, (or any other serial program in Linux) you must ensure that you have read/write access to the serial port. Do you this look at <code>/dev/ttyS0</code>:</p><pre class="code">rgetz@home:~> ls -l /dev/ttyS0crw-rw---- 1 root uucp 4, 64 2005-03-19 17:01 /dev/ttyS0</pre><p>You can see here that only the user <code>root</code> and the members of the group <code>uucp</code> have read/write access. To determine if you are in the group <code>uucp</code> check with the <code>groups</code> command:</p><pre class="code">rgetz@home:~> groupsusers dialout video</pre><p>The <code>root</code> user must add you to the <code>uucp</code> group either by editing the <code>/etc/group</code> file, or by using the distributions graphical interface. Before the new group will take affect, you must log out, and log back in.</p></div><!-- SECTION [1288-2258] --><h3><a name="kermit" id="kermit">Kermit</a></h3><div class="level3"><p> Kermit is very easy to set up.
