Hi

I have to compile a string and send it to an IP address.

the string needs to have this format

SOH>SOMETEXT<SPACE>SOMETEXT<CR><LF>

i have a char data[100] defined

i want to put the above string into the char data[100] i know how to put the text in using strcat, but how do i put in the SOH (0x01), Space (0x20), CR(0D)and LF(0A) around the string?

thanks
Tara

Hi,

you can use character escape sequences \xhh where hh is the hexadecimal number.

Code:

data[0]='\x01';

The CR and LF have their own escape sequence \r and \n and the space is just a space..

Code:

data[i]=' ';
