Note:
We recommend that you use either the YModem or the YModem-
G protocol. Use the XModem protocol if that is the only one you
have available to use.
~
The YModem-G protocol allows the fastest transmission of the three
types; however, this protocol does not acknowledge receipt of packets.
You can receive all files grouped under a subdirectory at one time.
~
The YModem protocol is a slower method of transmission, but is more
reliable because it acknowledges receipt of packets. You can receive all
files grouped under a subdirectory at one time.
~
The XModem protocol is a laborious method of transmission because
you must enter the filename of each file in the complete package of
software upgrade files to accomplish the upgrade task.
