I am trying to use the GSM breakout board. I'm using SotwareSerial to communicate with the module.
There is only one problem: the SoftwareSerial receive buffer is only 64 bytes long. This is not enough to get to the real SMS. Only the header and sender phone number is captured.
I found the SoftwareSerial.h file and know what to change.
My problem is that when I try to save the modified file I get an Access denied message.
It seems as though because this file is located in the "Program files (x86)" folder I don't have permission to change the file.
How can I get authorization to work in the SofwareSerial directory to be able to change the buffer setting and save the file to the original position?
