The softload facility in the TA supports the following 
functions: set/display softload password, request softload 
version information (on both active and alternate sets), initiate 
softload, and swap to alternate software.

The LCD menu supports the softload operation and remains 
fully operational while the softload is in progress. The status 
can be displayed by selecting DIAGNOSTIC OPTIONS? and 
DISPLAY STATUS SOFTLOAD?.

The status messages are shown in Table 13-2.

Softload operations must be initiated using the AT commands 
listed in Table 13-3.

The commands are described on the following pages.

A password must be entered to perform softload and swaps.

password. Any password changes must be made from the local
