<div><br>Hi,</div>
<div> </div>
<div>I am a bit confused about the kind of cable I need to use.</div>
<div> </div>
<div>I have read the wiki about the calypso serial cable at</div>
<div> </div>
<div><a href="http://bb.osmocom.org/trac/wiki/CalypsoSerialCable">http://bb.osmocom.org/trac/wiki/CalypsoSerialCable</a></div>
<div> </div>
<div>It says:</div>
<div> </div>
<p>The Calypso phones typically all have a serial port @ 3.3V levels on the 2.5mm earphone jack. </p>
<p>Those cables are sometimes called <i>T191 unlock cable</i>. </p>
<p>You can either buy ready-made cables, e.g. at: </p>
<ul>
<li>USB variant
<ul>
<li><a class="ext-link" href="http://www.gsmliberty.net/shop/motorola-t191-dataunlock-cable-p-1252.html"><span class="icon">gsmliberty.net</span></a> </li>

<li><a class="ext-link" href="http://gsmserver.com/cables/Smart-Clip_Cable_for_Compal_Chi_Mei_based_phones.php"><span class="icon">gsmserver</span></a> </li></ul></li>
<li>RS232 variant, you still need a separate standard USB/RS232 cable
<ul>
<li><a class="ext-link" href="http://www.handy-style.de/index/cat190/2130"><span class="icon">handy-style.de</span></a> </li>
<li><a class="ext-link" href="http://www.cellcorner.com/xshp/unlock-phone-codes/motorola-t190-t191-t193-unlock-data-cable.html"><span class="icon">cellcorner.com</span></a> </li></ul></li>
<li>USB/RS232 cable
<ul>
<li><a class="ext-link" href="http://www.tronisoft.com/cat_usbtoserial.php"><span class="icon">tronisoft.com</span></a> (FTDI and Prolific cables)</li></ul></li></ul>
<div>If you click on <a href="http://cellcorner.com">cellcorner.com</a>, you get a serial version of T191 unlock cable.</div>
<div> </div>
<div>I have purchased a similar cable not from that link but from a local shop near my home. (I am from India).</div>
<div> </div>
<div>The reason I have purchased the serial version is that the local shop only has the serial version.</div>
<div> </div>
<div>You have said in the wiki for the serial version, I still need a separate standard USB/RS232 cable.</div>
<div> </div>
<div>Why do I need a USB/RS232 cable ? </div>
<div> </div>
<div>If its a laptop, I can understand that they don't come with a serial port so you need the converter.</div>
<div> </div>
<div>Many PCs come with a serial port. </div>
<div> </div>
<div>Can I not connect the serial version of the T191 unlock cable to PC serial port?</div>
<div> </div>
<div>As far as I understand, the T191 unlock cable is used to convert RS232 signal level to 3.3V required by C128.</div>
<div> </div>
<div>I have a laptop and not a PC. It doesn't have a serial port. </div>
<div> </div>
<div>Since I was able to get hold of a serial version of T191 unlock cable as I told you in the begining of the mail, I also purchased a USB to Serial converter. Its a BAFO BF-810.</div>
<div>Its based on Prolific chipset.</div>
<div> </div>
<div>So I connected first the USB/RS232 converter ju(BAFO BF-810) and then the serial version of the T191 unlock cable.</div>
<div> </div>
<div>Is this the right way ?</div>
<div> OR</div>
<div>Can I just connect the USB/R232 converter (based on Prolific chipset) and the use a cable which contains DB9 female on one side and 2.5mm jack on the other?</div>
<div> </div>
<div>I am asking the second question because you have mentioned in the wiki under Hints and Warnings like this:</div>
<div> </div>
<div>If you don't use a 3.3V (low voltage TTL, LVCMOS) serial port you can fry your phone! (internally, it connects to the IO-pins of the baseband processor which run at 2.8V). <strong>Don't connect directly to your PCs serial port (running at +/- 12V!).</strong> </div>
<div> </div>

<p style="MARGIN-BOTTOM: 12pt" class="MsoNormal">At least on my Cygwin installation under Windows XP the serial port<br>is accessible as "/dev/ttySx" (x is "0" for COM1, "1" for COM2 and<br>
so on). All the USB to serial converters I am aware of are virtual<br>COM ports on Windows which means that they are accessible the same<br>way, e.g. if the virtual COM port is "COM7" it can be be accessed<br>as "/dev/ttyS6",<br>
