I've got a new SIMCOM GPRS modem. Following is the sceenshot at the client PC in Minicom:
at+cgdcont=1,"IP","APN"
OK
at+ciicr
OK
at+cifsr
OK
at+cipstart="tcp","remote server ip address","port no"
OK
CONNECT OK
at+cipsend
>I'm sending this data from the client
SEND OK
Here after issuing at+cipsend I get a promt '>' where I can type text and then I need to press ctrl+z which will send this data to the server. How do I write these sequence of commands in a file or a scipt in Linux? How do I capture ctrl+z also?
Please do respond ASAP. Thanks
Sandeep.

I'm using the SIM100 module GPRS SIMCOM modem. I connected the modem to my Linux system serially and was able to communicate with it properly.
Now I have one target board(with linux on it) having wavecom modem on board. Thismodem has 15 pin female connector. and on board there was on 15 pin male connector of which only 3 pins tx,Rx and Gnd were being used. Linux on flash was connected to this modem serially .That also was working fine.
Now I want to use this SIMCOM modem and not the wavecom modem on my board. so I removed(desoldered) that male connector from the board and soldered the 3 pins of the 9 pin male connector. which was then connected to the SIMCOM modem. But modem is not able to respond to the terminal program.
Is connecting only 3 oins is sufficient?

Some SIMCOM modems have hardware flow control activated by default. Tie RTS to GND and try again.

Yes on modem side I short pin7(RTS) and pin5(gnd) and tried but problem still there.. But what is the point in shorting these pins when they are not connected to the board. Board has got points for only 3 pins?

In wavecom modem Rx(pin 32) is output & Tx(pin 39) is input whereas in simcom
it is exatly inverse convention Rxd(pin 40) is input & Tx(pin 42) is output.So u will have to interchange Rx & Tx connection for this problem.For more details
datasheet attached herewith.why r u using sim100 it being absolute now?

I connected DTS,DCS,CD together and RTS,CTS together as suggested by *gorkin* earlier and the modem is resonding to the terminal program. This means that the board is using the llopback handshaking.
for more details on this check the following link:

Dear Samloyer,
Is there a development kit available for M22
Added after 5 minutes:
Hi All,
I am new to this field. I need to learn how to develop GSM car alarm with Benq M22 or SIM100 module. Can someone help me with this or give me a link to good document. Basically I need to control O/p with SMS and receive SMS from the module when certain I/n is activated.
How do you program M22 and/or SIM100. Are there development boards for these like for Sony Ericssion GR47. Where can I find good documentation on these
Thanks
Wicky

Wicky, frey_berg:
I've got the prices from China for SIM300 GSM modules, from www.fanwell.biz:
$40/pc for samples 1pc-10pcs
$36/pc for order 100pcs
$35/pc for order 1K
Also they are able to supply SIM300 board connectors, SIM holders and GSM antennas
What do you think about their prices ?
Is something there in China more cheaper price ?

Our firm proceeds to the production of equipment on the modules of SIM300.
For preparation to application and setting of necessary us parameters we tried
to utility engineering - "services_tool (change_tool) V1.00"
Unfortunately part of necessary us functions does not work in the program.
We want to ask you more update version of software.
Best regards

Nice library tramp! Do you by any chance sell single unit of SIM300 modules? The inventory page is a bit confusing - it has a price for a single unit but under "package" it says that they come in 100 quantity? (assuming alta-vista translated package correctly 
Thanks
