I want Few AT commands of SIM300 GSM

I am using hyper-terminal in winxp..
So what will be the AT command of followings :

1)Auto-answer
2)Read incoming caller number.

THanks

AT+CLIP=1

it is used to Read incoming caller number

AT&F; make sure it returns OK.
Type: ATS0=1 (that's s-zero equals 1: tells the modem to answer on the first ring)

see a detail here

Friend... Thanks A lot................ both codes are working great............. Thanks again..
Now what will be the AT commands of following :
1)Disconnect incoming call
2)Receiving DTMF tones.

Thanks again...

@ yusuf.hobbist
which modem you are using
normaly at commands are same for every modem
but in dtmf at commands are little bit different

ATH

is used to Disconnect incoming call

ok ! thanks
But If I press 1 on my Mobile then I will get DTMF tone on my modem ..
SO how do I switch my appliance according to my tone...
That is I want to receive dtmf tone in micro-controller and switch appliance... without DTMF decoder..

thanks

@ yusuf.hobbist
use a DTMF circuit to get the binary equivalent of the tone
according to that do coding in the controller to match the binary of DTMF
and control the devices
when you press 1 DTMF decoder give you a binary of 1

0001

here is the basic circuit for testing

Thanks majoka for you help..
can you give me the AT Code of following :
1) Check whether Modem is On or OFF ?
2) Check if the network is registered or not ?
3) Check signal strength..

what is GPIO0 , GPIO1, AND GPIO8 , And how do we use this...

And please visit following link GSM BASED MOTOR CONTROL : http://www.nskelectronics.in/gsm_based_motor_control_.html and download it's manual..
I have look several times it manual ... but I cant understand how it is working without micro-controller..
As you will read it's information on it's page you will not find any information of micro-controller..
And there is no micro-controller in Image also... So, how come the two relay energize for 5 sec independently.. and how does the following commands work without micro-controller...

Storing Master No Thru SMS
SMS To Get The Status of device
Missed Call To Control - Motor On and Off
Message Alerts for Power UP , Motor On, Motor Off , Status

Thanks

I didnt got any reply
