The module treaty is "Ftp2" Obj-C (Mac OS).
If TLS (AuthTLS=true) mode has been activated, the "BandwidthThrottleDown" property does not work (no limit)!
Otherwise if I connect in "clear mode" (nothing Encryption) it works.
I also tried to clean (no TLS) the "Control Channel", after connection, and with DataProtection to "private"; but the "Channel Data" is not encrypted!
Help me, Please!
