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
