Hello,
I am Electronic Engineer and have to explain my project first to let you
better know, which solution I need...
OK, I am accessing the Internet throzh GSM (GPRS, EDGE, UMTS and HSDPA)
have now obver 20 differnet PCMCIA crds and 8 different USB modems here
but they are ALL crap, even if the internet access is mostly working
perfect.
What I need is:
1) Access the Internet by choosing which protocol
(CSD, HSCSD, GPRS, EDGE, UMTS or HSDPA)
2) sending and receiving SMS
3) phone calls.
The problem is the 3), and so I have build my OWN hardware. I have
bought a GSM chip from NXP, a Serial/USB converter chip, a USB-SoundChip
and a 7 port USB 2.0 hub. Also I have a small I2C EEPROM conected to
the Hub to let the host system know whats going on here...
OK, now if I connect my Hardware to my ThinkPad 570, it is nicely
detected and I get a /dev/ttyUSB0 and a /dev/dsp2.
OK, using "ppp" I can configure the /dev/ttyUSB0 for internet access!
Hey *, it is JUST working! :-)
Now disconnecting, I can use AT-Commands to call a number and... I can
phone over the newly added soundcard with someone.
Using "smstools" I can receive and send SMS too.
So, my selfmade hardware is working from scratch with Linux. ;-)
And yes, if all is working fine, I will go into producion and sell it
over my Web-Site/OnlineStore.
Now I run into trouble, since the GSM-Chip allow PhoneCalls and Internet
connections at once, but I do not know, HOW to send those AT commands.
If I connect to the internet, I know, it is possibel to send AT commands
inside a frame of a datastream, but how can I do this?
It seems, I need a modified version of the "pppd" which then should
support sending/receiving of raw SMS (encoding can be done be external
programs) and of course PhoneCalls.
So my idea is, to drop "pppd", "smstools" and "phone software" and build
a GSM daemon which then can handel this stuff @once.
Question: Is this possibel with Perl?
Thanks, Greetings and nice Day/Evening
