In the Open from FTP dialog, use the 'Permissions' button after selecting a file or directory.
Point of clarification (v12.20, 3/2007):
On the initial file save (via "File/FTP/Save As To FTP"), the file is saved using 'default' permissions ('600' in my case).
The permissions of the file can then be updated by doing another save via "File/FTP/Save As To FTP") and "browse site" to the filename, clicking on the "permissions" button, and setting permissions ('755' in my case). Clicking the "permissions" button sets the permissions, and you can then cancel out after clicking the "permissions" button.
Subsequent "Save As to FTP" will use or leave the newly set permissions ('755' in my case) unchanged.

If anyone knows of a way to establish default permissions within UltraEdit itself for the initial "Save As to FTP", please post it here.
