When preparing to initiate a download procedure, choose either a full or partial
download and the COM 2 port, through the system mode menu options (refer to
Chapter 4). Depending on the type of files you are downloading and the download
method you are using, there are some restrictions on whether a full or partial
download is permitted.

Description and Effects
An entire application, including all executables
and data files, transfers from one system to
another in a single operation.
Files related to the file authentication process
and device configuration settings can be
included in a full application download. During
this process, SRAM is cleared.
Following a full application download, the
device restarts and the file authentication
module is invoked. If application files are
authenticated and config.sys *GO variable is
set, then the application executes.
A subset of application executables, font files,
or data files transfer from one system to
another to modify or update an existing
application.
Files related to file authentication and device
configuration settings can be included in a
partial application download. During this
process, SRAM is not cleared.
Following a partial application download, the
device does not restart and returns control to
system mode or the issuing application. The
file authentication module is not invoked, nor
are any applications allowed to execute, until
the device is manually restarted from within
system mode.
