Change transfer parameters

I use script to upload file.
What parameter in script i should use to avoid change of file name?
For example:
By default in Transfer Tab (Preferences Dialog) parameter "Filename Modification" set to "Lower Case"
I want override this settings in script and transfer file to ftp-server without changing file name case.

It is not. By default it is set to no change.

Please read FAQ. If that does not help, come back.
