| Nokia 6190 Data Cable
               I recently got a new job and with it, a cellular phone. In this
              case it was a Nokia 6190. And, being a hardware hacker, I just had
              to personalize it. Plus, I wanted to have the ability to use my
              phone with a modem for remote access. So, I needed a cable that
              connects between my serial port and the 6190. 
              Surfing the web one Saturday morning I stumbled onto this
              design at http://jeff.trilli.com/6190.html.
              Here is the text that explains the function of the cable and it's
              capabilities: 
              The cable that I made works with Nokia Data Suite 1.2a and
              2.0. All you have to do is connect it to a standard PC serial
              port. No additonal PCMCIA modem is required. This is what makes
              GSM so great! I have used it to make data calls and connect to the
              Internet on the FIDO GSM network. It works great at 9600! The
              cable also allows me to organize my phonebook entries, send SMS
              (text messages), upload new ringtones and graphics that I made to
              my phone. Here is the schematics for the connector:
