I have to write a program to display the same output. My instructor told us in class to save the capture session in binary format then just convert binary to ascii. I have used the save option under the file menu and saved file type as libpcap. This does not save the file in binary format, when I use emacs/ textedit to view this file it is anything but binary.
The libpcap format *is* binary. Believe me or see: http://wiki.ethereal.com/Development/LibpcapFileFormat
You may see packet *content* being text, e.g. if you capture an HTTP stream while getting some text/html files. The content inside the libpcap file is not being encrypted or compressed or something like that, so you may see plain text packet content as, well, plain text.
