Transfering a file using C++

[amateur¬]

Right so what I'm trying to do is to take a text file i.e. in Notepad/MW from disk, encrypt it and transfer it to another computer where it will be received, decoded and stored on disk as a plain text file. I have to use the COM1 serial port to do this transfer. All code needs to be in asm86.

As my name suggests, I'm inexperienced with C++ programming...that means no experience whatsoever so I would appreciate any help given for example, websites which will help to develop my C++ skills to aid me in this particular topic or alternatively if you want to write me the code - please write down the reasons each line of code is written the way it is so I can learn from this.

Be in touch.

You forgot give us your email so we can send it there after we have written your program.
