 RFC 1974
When the Stac LZS compression protocol is successfully negotiated by the PPP Compression Control Protocol [2], the value is 00FD hex or 00FB hex as described in section 2.
Friend and Simpson Informational [Page 13] RFC 1974 Stac LZS August 1996 (A single logical connection.) When the History Count field is set to a value greater than "1", separate history buffers, error detection states, and signaling states are maintained by the decompressing entity for each history.
The Stac LZS protocol provides a means to detect these error conditions: LCB or CRC for erroneous datagrams, and sequence number for dropped or mis-ordered datagrams.

 Dr. Dobb's | Undocumented Corner | July 22, 2001
While the large patent-infringement award to Stac seems like the big news, the smaller trade-secret award to Microsoft is at least as interesting, because of its direct connection to reverse engineering and the use of undocumented interfaces in the PC software industry.
Stac never saw Microsoft's source code; it learned everything it needed using Soft-ICE on the binary MS-DOS code, but the jury may have thought that Stac had taken MS's source code, viewing this as parallel to MS's infringement of Stac's patent.
Still, the Stac verdict does seem to establish the right for a company such as Microsoft to declare, out of the blue, that one of its undocumented interfaces is suddenly a trade secret.

 Making Microsoft Safe for Capitalism by James Gleick
One company that tried was Stac Electronics, which had developed software that used a compression technology to effectively expand the capacity of users' disks.
Microsoft wanted to build Stac's technology into the operating system and negotiated in its usual scorched-earth style, demanding a worldwide license for a one-time flat payment and threatening to move ahead with or without Stac's license.
Stac now exists as a happy Microsoft partner and the disk-compression business is no more.

STAC sued MS on charges of infringement of one of it's patents for the Stacker Product which MS copied into MS DOS 6.0

Still other readers railed at some of Microsoft's past bad conduct--- and I completely agree that Microsoft has done some truly reprehensible things to competitors, with its treatment of Stac Electronics in the 1980s leading the list.
But Stac properly sued and won a large settlement from Microsoft.
And there are venues for doing so, as Stac's enormous (and justified) settlement shows.
