Open the AXF in ArcPad Studio. Right click and select "Command..." then, the rest is SQL awesomeness.
For example, querying the sync properties can be done by:
SELECT *
FROM AXF_PROPERTIES
WHERE NAME = 'AXF_SYNC_PROPERTIES';
Syntax for changing it is:
UPDATE AXF_PROPERTIES
SET VALUE = '...'
WHERE NAME = 'AXF_SYNC_PROPERTIES';
If the property doesn't exist, syntax for creating it is:
INSERT INTO AXF_PROPERTIES (NAME, VALUE)
VALUES (
'AXF_SYNC_PROPERTIES',
'...'
);
You can even execute the statement in an ArcPad applet with something like:
Map.Layers(1).DataSource.Execute sql
