/***************************************************************************
Name : COMDEVI.H
Comment : Controls Comm interface used by Fax Modem Driver. There are
4 choices.
(a) If UCOM is defined, it uses the WIN16 Comm API as exported
by USER.EXE (though eventually it gets to COMM.DRV)
(b) If UCOM is not defined and VC is defined, it uses the
COMM.DRV-like interface exported by DLLSCHED.DLL (which
merely serves as a front for VCOMM.386)
(c) If neither UCOM nor VC are defined, it uses Win3.1 COMM.DRV
export directly.
(d) If WIN32 is defined (neither UCOM or VC should be defined at
the same time), it uses the WIN32 Comm API
Functions: (see Prototypes just below)
