Description: Specifies the maximum level of compression supported for inbound data. The local LU uses this value in conjunction with appcLluAdminCompression for negotiation during session activation (SNA BIND). none - specifies that no compression is to be used. rle - specifies run-length encoding compression in which a 1 or 2 byte sequence substitution is used for each repeated run of the same character. lz9 - specifies Lempel-Ziv-like compression in which 9 bit codes are used to substitute repeated substrings in the data stream. These codes are indices that refer to entries in a common dictionary generated adaptively at both sender and receiver as the data flows and compression occurs. The larger number bits used for the code, the more storage space is required for the dictionary, but the larger the compression ratio. lz10 - specifies a 10 bit code Lempel-Ziv-like compression. lz12 - specifies a 12 bit code Lempel-Ziv-like compression.
