I have an embedded platform that is connected to my Windows PC via the serial connection. The embedded application sends 532 bytes through the connection. Using HyperTerminal, I am able to see the incoming (non-text) characters in the terminal window. However, I am trying to save the stream as a binary file. The problem is that when I choose to 'Receive File...', the dialog that opens (after asking for a file name and location) does not have a stop button, so my only option for stopping the reception is through canceling, which discards the captured data.
It appears that although I am not sending pure text, I can use the 'Capture Text...' menu. Then, I can manually terminate the reception of data. There are two problems, though - first, the new data is appended to the existing file (if there is one), and not replacing it. Second, the terminal adds a 0xff byte at the end of the file (signaling end of text file).
So, how do I save a binary stream to a file?
