I found also the data cable **DLR-3**: note that data -cable for lower models (**DAU-9P** and the like) doesn't allow to use the modem -(it's possible to use 51xx and 61xx phones for data trasmission with those -cables, but only under Windows with a software modem). - -Having the cable, we can test it putting it between the phone and a computer -with a RS-232 serial port. With a terminal emulation program: - -In the picture you can see how to the ati (identification) commnad, the phone -answers with its name, and to the ati2 command, it asnwers with the version -number of its software. - -But the Newton has no RS-232 port! -`````````````````````````````````` - -Yes, this could seem a problem at first sight. On the other hand, as many know, -with the special serial adapter (dongle) it's possible to extract a RS-422 (Mac -serial) from the Newton; moreover, RS-422 is compatible with RS-232: just -connect the right wires. I did it this way: (pinouts are connector side): - -+------+------+ -|RS-232|RS-422| -+------+------+ -|1 |2 | -+------+------+ -|2 |5 | -+------+------+ -|3 |3 | -+------+------+ -|4 |1 | -+------+------+ -|5 |8 & 4 | -+------+------+ -|6 |2 | -+------+------+ -|7 |1 | -+------+------+ -|8 |2 | -+------+------+ - - -On the Web you can find several texts about different serial interfaces: the -search is left as useful exercise to the reader. - -To test the adapter, link everything up (phone - DLR-3 - adapter just built - -dongle - Newton) and use a terminal emulator on the Newton: - -The program used is `PT100`_ - -What about the Internet? -```````````````````````` - -All right, at this point the only thing missing is using the phone to connect -the Newton wirelessly to the Internet. You'll need `Newton Internet Enabler -version 2`_, and `Modem Modifier version 2.02`_. - -Here you can see the settings I use (the links are to a text version of the -same). - -There are some details to clear: - -* 2800 is the phone number of `Omnitel`_ (Vodaphone group) Internet access. - It seems to be the cheapest in Italy. - -* There's no need for username or password, since the authentication is done - by the SIM card. - -* The DNS number **is NOT official**: it would get sent during PPP - handshaking, but the Newton doesn't understand it. The information come - from an Italian web page (`Come accedere a Omnitelnet 2800 da Linux`_). - **DO NOT** use this number if you are not using Omnitel's service. - -* Configuration strings have been taken form the .INF file for the 7110 - installation under Windows. - -* Someone might have noticed that the +CBST=0,0,1 command has been changed in - +CBST=75,0,1. This allows the phone to connect at 14400bps instead of - 9600bps. The information comes from an Italian web page (`Portel`_). In - some areas, the phone will not correclty establish the data connection if - set for 14400bps. I have made two modem profiles, one for each speed. I - still need to find a way to discover which one to use without trial and - error (and paying for two calls). - -Enjoy! - -.. _`pt100`: - http://www.scrawlsoft.com/products/pt100/info.html - -.. _`portel`: - http://www.portel.it/news/news2.asp?news_id=1563 - -.. _`richard avery`: - mailto:rjavery@mail.com - -.. _`come accedere a omnitelnet 2800 da linux`: - http://www.pluto.linux.it/ildp/journal/pj0003/omnitelnet2800.html - -.. _`newtontalk`: - http://www.newtontalk.net/ - -.. _`two`: - http://www.chuma.org/newton/ntalk-archive/ - -.. _`7110`: - http://www.nokiausa.com/phones/1,2499,;;rt7100,FF.html#7100 - -.. _`archives`: - http://www.newtontalk.net/archive/ - -.. _`nokia 6210`: - http://www.nokia.it/cellulari/6210/home.asp - -.. _`newton internet enabler version 2`: - http://www.unna.org/unna/apple/internet/NIE2/ - -.. _`omnitel`: - http://www.omnitel.it/ - -.. _`modem modifier version 2.02`: - http://www.unna.org/unna/utilites/ModemModifier2.02/ |
