S25 comprises to its inside modem in compliance with the ITU-T a V22bis standard (transfer to 2400, 4800, 9600 bits/sec, with given programs that take advantage of the jam arrive to one speed of transfer of 38400 bits/sec!!!). The Modem physically is connected to the Irda port of the cell., it is understood that the data will be sended from the application through the Irda port to the modem and receipts in the inverse distance.
if you not installed S25 Modem to Pc, click here.
Before beginning to analyze code it is well to examine an exchange example given taking advantage of HyperTerminal di Windows: From the menù " Formulations - > Way FAX/DATI " of telephones activates the voices " Irda " and " It receives FAX/DATI ", we put in optical correspondence the Irda sensors of the PC and the Cell or connect the cable Siemens. We launch HyperTerminal, it will ask a name for connection: we write "S25", subsequently we select port COM that heads for the Irda connection of the cell. To this point we have established a dialogue with the modem of the Cell.

Like preannounced, being a Modem to all the effects, will answer to normal commandos AT, as an example digitando: "ATDT" we will visualize the state of the modem. Handbook of specific commandos AT for S25 to the hand, we are ready for read/write/set the formulations of the Cell. As an example digit "AT+CBC=" we will be able to know the level of loads with the battery,

with " AT+CSQ=" we will print to video the power outlevel signal, etc.
This is only a small example of what we can make, is present commands AT for the reading and the writing of the agenda, of the calendar, for the SMS shipment and other anchor, the introduced examples JAVA implements only a part of exposed how much.
