if you type at the hyperterminal the command the gsm will take it.

You can use Docklight which is more friendly to use.

i maid ascii set up..now commands are visible but no respond from the terminal..means commands are not executing..i also called to my modem from my cell its showing "ring"..means the gsm is working correctly...the question is how to execute commands
 

If using Hyperterminal, after typing AT command, you hit the 'enter' button on keyboard. or what? enter using microcontroller?

As far I understood you are positive that your modem is working correctly and you can succesfully receive bytes from the modem. So if those assumptions are correct, then the problem could be on the transmit line. For some reason commands do not reach modem's Rx pin. Did you try the loopback test to verify your transmit line?

The following link will lead you at the exact desired post.

no question of cable problem because iam using cable with microcontroller for connecting it to pc..its working correctly..
 

Pls I really want to know if you can tell me any software I can use to be able to use my laptop as an Hyperterminal. Hyperterminals are usually in widowXP systems but i have Vista on my laptop and I dont seem to have an Hyperterminal on my LAptop so please which software can i use for the purpose. thanks

It is much more advanced than hyperterminal, but not free.

Try to get 'rsterm'...
It is a terminal program that supports Windows 7..
Its easily available..
 


for windows vista and windows7 you can use "Docklight hyperterminal",,also its user friendly:arrow:
 

Use TeraTerm. Hyperterminal absolutely sucks, I have no idea why so many electronics enthusiasts use it.
 

Thanks a lot. Please I have downloaded the Docklight and its review manual I'll see how to use it today. But it was free (3Mb), And from their website, i hope it works. Opopson
 

set the flow control as "XON/XOFF" and check
