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/ |
