Gets or sets the length of interval between NOOP commands sent during transfer when the KeepAliveDuringTransfer option is enabled.
The length of interval, in seconds, between successive NOOP commands. Default is 600.
Minimal value is 60. Setting this to a value lower than 60 will set it to 60.
The KeepAliveDuringTransfer option is only needed if the FTP control connection is otherwise being dropped by a buggy router or firewall while a very long data transfer is in progress.
