AT command in binary code


#1

Hello,
I’m new in this, I haven’t reed all the AT command manual but, how does an AT commands looks like in binary code?
Is it just an ASCII conversion or is it different?
Example:
AT+CSCS=.
can be “GSM” or “PCCP437” or “CUSTOM” or “HEX”

So for GSM

In HyperTerminal the syntax would be?

AT+CSCS=”GSM”
Or
AT+CSCS=GSM
Or
AT+CSCS=
Which one?

And in binary code how would it look like?

Also, does any body know how to download a firmware update; I have been looking for and didn’t fins the way.

Thanks

That is absolutely fundamental - you really need to do that!

Yes, AT Commands are just plain ASCII-Coded text.
(this applies to all modems - not just GSM modems)

See the AT Command Manual: This applies to the way the modem handles the content of SMS messages - it doesn’t apply to the commands themselves.

See the AT Command Manual: the use of quotes, etc, is as shown there.

Again, AT Commands are just plain ASCII-Coded text.
