Stacker is an LZS compression algorithm that can be used in conjunction with
PPP to provide more bandwidth on a given link by compressing the packets,
this is not a hidden command details can be found here

or.....
Data compression is designed to decrease the size of a frame and enhance
throughput across a relatively slow link. A detailed discussion is outside
the scope of this document, but a brief discussion follows.
See WAN Compression FAQs and Compression White Paper for more information.
Compression algorithms used for data are lossless, meaning that they
reproduce the original bit streams exactly without degradation or loss.
Cisco IOS. software supports an optimized version of the STAC (LZS)
compression algorithm that provides good compression ratios, but requires
many CPU cycles to perform compression.
Depending on the router platform, you can implement data compression on a
Cisco router via one of three methods:
Software-based compression as a Cisco IOS feature executed on the central
route processor.

Paul,
It appears that ppp compression stacker is a hidden command, but when I
tried it the router simply added 'compress stac' to the config. I wasn't
able to find any documentation regarding 'ppp compression stacker'.
