3-3-2-4 Making an IrDA (infrared) connection
Before it is possible to make an IrDA connection make sure the IrDA port of the IrDA
device is turned on.
Before trying to make an IrDA connection always make sure the IrDA port of the
OPL9724 is in line of sight of the IrDA port of the IrDA device.
3-3-2-4-2 Making an IrDA connection with a mobile phone
To turn on the IrDA port of a mobile phone search for the IrDA option in the menu
structure of your mobile phone, then activate the IrDA port of your mobile phone.
3-3-2-4-2-2 Sending data using the GPRS network of the mobile phone
Before you try to establish a bluetooth connection using the GPRS network make
sure your mobile phone has a working GPRS subscription.
The advantage of using the GPRS network is that you don’t have to enter a telephone
number, username and password of an ISP server. Besides this, establishing a
GPRS connection will go much faster then establishing a connection with ISP server
using the GSM network.
3-3-2-4-2-2-2Sending the data file the remote FTP server using GPRS
After establishing the GPRS connection the software will try to connect to a remote
FTP server, by using its IP-address, a username and a password. The data file will be
placed in the root-directory of the FTP-server.
3-3-2-4-2-2-3Email the data the remote SMTP server using GPRS
After establishing the GPRS the software will try to connect to a remote SMTP server,
by using its IP-address, the senders-email address and the recipients emails address.
Before connecting to the SMTP server a connection with a POP-server is first made
to let the OPL9724 authenticate itself at the mail-server. To do this the IP-address of
the POP-server and a valid username and password needs to be specified as well.
3-3-2-4-2-3 Sending data using the GSM network of the mobile phone
Sending data using the GSM network of a mobile can be compared with sending data
using a wireless modem. This has the advantage that is possible to dial-in to a remote
modem or server at almost any location. The disadvantage of using a mobile GSM
connection is that it’s usually much slower then a serial modem (normally 9600bps)
3-3-2-4-2-3-2Sending plain ASCII data to a PC using GSM
Before connecting, the remote modem should first be initialized with ‘ATS0=1’-
modem command so that the modem will automatically go off hook and connects
when being called.
A serial communication program, like HyperTerminal or Procomm Plus, should be
used to be able to initialize the modem and view the received plain ASCII data.
After setting up the IrDA connection the software calls a telephone number of the
remote PC with a modem using the GSM network of the mobile phone. As soon as
the connection with the remote modem is established the data will be send a plain
ASCII data.

Kermit protocol.
