 My memory is that fossil was needed, because the was a difference between
 the IPM PC and the DEC rainbow, inthe way the seriaport was handled.

 With Fossil that difference was covereed in a special layer and Fido,
 Seadog and Opus had a single interface to run on IBM PC or DEC Rainbow.

 Other uses of the Fossil interface followed later.
