Yes, I'm getting the data returned from the SMS gateway, and assign each line of the return string into B$, C$, D$ ... ...
I have check the return string with PC, this should be 3 lines of return string. In PLC, first line and second line are missing, third line just show the last few letter. When I total up this 3 line, it is about 77 characters. I think, may be something wrong with the CR-terminated string in the first and second line of return string, then it join become 1 line.
How to read out the string from the buffer?
