FTP, File permissions

[Tim Drake - E41]

  Hi, this may be a well known problem, but its my first encounter.
We're transfering files from a pc to a unix host (using FTP's sw on
the pc). The problem is that ftp leaves the files' permissions set
to 666, we'd like them to be 644 or 640. Is there a way to do
this with FTP ??

    Thanks Tim Drake
