Hi all,
I'm using a eZ430-F2103 microcontroller to control a GSM modem. My problem is I don't know what is supposed to happen when you send an ASCII character to GSM modem from the microcontroller. Will the GSM modem respond me back with the same character? Is it just simply sending ASCII characters or there is more to it?
Thank you
Rui
"ATE command which is supported by number of GSM modems"
I'd be fairly confident to say that this is available on all modems that support AT commands - not just GSM modems!
"the characters are not echoed and in this case you cannot see the characters which you type, on the Hyperterminal"
To be precise, the characters are not echoed by the modem - so you won't see what you type unless you set your terminal to local echo.
If you set your terminal to local echo and enable echo on the modem (ATE1), you will see double!
