+Introduction

+------------

+The ft991 utility is an interactive tool for backing up and restoring both

+the memory settings and menu settings of the Yaesu FT991 transceiver.

+Individual memory locations store information about frequency, repeater

+offset, signaling, tags, modulation, and clarifier.  Menu settings store

+configuration information about current menu options and parameters.  The

+utility also has a pass through mode for sending CAT commands directly to

+the transceiver.  This feature is useful for future code development and

+debugging.

+

+The ft991.py module encapsulates the FT991 CAT commands and handles low

+level serial communication to and from the FT991 usb port.  CAT commands

+are encapsulated according to object oriented methodology, that is, 'set'

+to send parameters and settings to the FT991, and 'get' to receive status

+information back from the FT991. Additionally ft991.py contains helper

+functions for parsing data read from backup files. The 'set' functions
