Jeff,

Attachment is okay, but is gzipped. On a Win98 system, I just now downloaded the file, changed the extension to .gz (didn't know WinZip was fussy about extensions) & was able to unzip the file, then read uncompressed file with Ethereal.  The file only has the two frames that I was concerned about.

Thanks,

Phil
