Hai, I am using this an array to do that.
char controlZ[2] = {0x1A,0x00};
 
Hi,

I had tried with hyperterminal to make a call ATD9994238372; and press enter, it is working. Now i have to sent this command from my microcontroller to gsm modem. what is the hex value for "enter" key? Please do let me know.

Thanks,
V.Prakash
 

@prakashvenugopal: It is very likely that two more characters will be needed.
One is the "ESC" character and the other one is the "LF" (line feed) character.

LF = 0x0A
ESC = 0x1B
 
HI,


What is the AT command to set these parameters:
1) baud rate -1200 bps
2) data bits -8 bit
3) Parity - None
4) stop bit - 1
5) Flow control - None

Please let me know.

Thanks,
V. Prakash
 

Hex value of CTRL+Z is 0x1A. If you are writing your code is C, then use this, "unsigned char ctrlz=0x1A;" or if it assembly, then use this "MOV SBUF,0x1A"

It would help if you mentioned which modem you are using. I don't know if it is the same command for all modems.

I am able to access ctrl+z using 0x1A. No issues in it. I have to need the AT command to set the above characters.
