Thanks.

What do you mean "open to?"

ifstream readCOM;
readCOM.open(com1, ios::in | ios::binary);

readCOM << ''test'';

Is that you are talking about?

C++ Style:

ifstream readCOM;
readCOM.open(com1, ios::in | ios::binary)

char *ptrStore;

try
{
ptrStore = new char[SIZE];
}
catch (bad_alloc error)
{
cerr << error.what();
exit(1);
}

readCOM.read(reinterpret_cast (ptrStore), SIZE);

How do you get the exact size of whatever you're reading from the COM port? It is not a measurable storage container.

Do I have to use an MFC class? What is the major difference if I were to use the ifstream and ofstream instead of an MFC class? I have no experience with MFC or windows programming.

The biggest problem is that you have no control over the baud rate, secondly you can''t check the modem/line status bits.

You need to look into the Win32 communication functions
