Hello everyone,

I need some help to send a character over to my GSM Module.

Does anyone knows how to send Control Z via Uart ?

I've tried many possible combinations to no avil. Any kind souls around ? Been stuck hours trying to solve this.

strcpy(msg,"Sent From MCU" +char(26));
UART_Send(LPC_UART3, (uint8_t *)msg , strlen(msg), BLOCKING); //strlen :Length of Transmit buffer Checking Blocking.

You can use the octal form as an escape sequence

strcpy(msg,"Sent From MCU \032" );
UART_Send( ....

What is this ?
You don't want to use BASIC or C#, do you ?

C does not have a dedicated string data type, only character arrays.
Look for the [B][FONT=Courier New]strcat()[/FONT] [/B]manpage, how to concatenate 'strings' together.

As cmcquaid suggested, you can embed character constants in strings with a leading backslash, either octal ('\0<nn>'), decimal ('\<nn>') or hexadecimal ('\0x<nn>').
