Two new questions for me, probably not so new for others. Now that I have a description of the Binary II protocol, and I think I understand it I can play with it on my own, but... 1) How many different compression schemes are there? and 2) by schemes, I mean how many different algorithms are there out there? and 2) If there's more than one compression algorithm in use, doesn't that create some problems? How is everyone dealing with this? Luther Atkinson@VCUVAX.BITNET Atkinson@ruby.vcu.edu

Currently, Binary II itself has no compression. A program written by Floyd Zink called BLU added a single compression - Huffman (similar in concept to the sq command of cp/m I believe). There is a field in the bny header that I believe floyd uses to indicate compression. Floyd is working on a new generation of BLU called BLU II. Supposedly it will handle multiple versions of compression. Floyd has indicated to me that the first generation may only have the Huffman, but he wants to add the LZW compression soon. Note that I understand that ALPE's ACU is a similar program to BLU II (and is also written by Floyd). -- Larry W.
