Description
Initiates the YMODEM-BATCH file extraction protocol.
Customization data stored in a battery-powered NVRAM should be backed-up on a PC so
that, if a battery failure or other problem occurs, recovery will be possible without having to
re-enter data by hand.
Backup can be accomplished in three ways:
•
By loading and querying parameters one-at-a-time
•
Extracting binary data using the host port
•
By standard YMODEM-BATCH file-extraction protocol
The YMDO command is used to initiate the YMODEM-BATCH file extraction protocol. The
protocol allows one (or more) data structures to be extracted from the generator as binary
files. Each file contains all instances of a particular type of data. For example, the
FORMAT.MEM file contains all of the user-defined formats stored in the generator. Note
that ALL will cause all files except SYSTEM.SYS and FIRMWARE.BIN to be extracted.
YMDO internally executes PKUP before sending files, so PKUP does not need to be sent
before YMDO.
