/*
bestfcom.c - model specific routines for Best Power F-Command ups models
This module is yet another rewritten mangle of the bestuferrups
driver. This driver was written in an attempt to consolidate
the various Best Fortress/FERRUPS modules that support the
'f'-command set and provide support for more of these models.
Models tested with this new version:
FortressII LI720
FERRUPS FE2.1K
FERRUPS FE4.3K
FERRUPS FE18K
FERRUPS FD4.3K
From bestuferrups.c :
This module is a 40% rewritten mangle of the bestfort module by
Grant, which is a 75% rewritten mangle of the bestups module by
Russell. It has no test battery command since my ME3100 does this
by itself. (same as Grant's driver in this respect)
