Copying byte array with RS 2. Serial Port access, C. I am new to C, and I am working on a C application that communicates with a serial port using the Serial. Port class. I am able to send and receive bytes from one serial port to another. I am trying to copy bytes from one byte array to a new byte array. I only want to copy the bytes in the array that are from the 3rd index in the array to the next to last element of the array. When I try to copy the source array to the destination array and run my program, I get the following error message in Visual Studio Error opening my port Source array was not long enough. Use this class to control a serial port file resource. This class provides synchronous and eventdriven IO, access to pin and break states, and access to serial.
