Xterm logging on Cygwin/X - binary data in log file.

I have Cygwin/X installed on Windows 7. In an xterm, I turned on logging via Main Options > Log to File.

When I open my log file with Vim I get a warning that it might be binary. Looking through the file I see what I think are VT datastream escape characters. It makes it hard to use the file as a record of commands entered and results.

Should I be viewing the file another way?
Is there a better method to achieve my goal of keeping a log of what I've done. I could probably increase the scrollback buffer and use copy/paste but I am trying to avoid that.

$ xterm -version
XTerm(308)

$ cygcheck.exe -V
cygcheck (cygwin) 1.7.30

Thanks,
Gary

The log file contains everything unfortunately; unprintable characters, screen management sequences, et al.

You could open it with a hex editor to see what went on, but you'll need to interpret what you see.

You can't send it to a printer or anything like that. If you do you'll only do it once!!!

You editor is warning you that it might be binary because some of it is unprintables. Try a hex editor.
