ftp = chilkat.CkFtp2()

ftp.put_Hostname("ftp.example.com")
ftp.put_Username("login")
ftp.put_Password("password")

# To use FTP bandwidth throttling, set the BandwidthThrottleDown
# property to a maximum desired bytes/second:
# This example limits the download to 50K per second.
ftp.put_BandwidthThrottleDown(50000)

# The default data transfer mode is "Active" as opposed to "Passive".

# Connect and login to the FTP server.

# Change to the remote directory where the file is located.
# This step is only necessary if the file is not in the root directory
# for the FTP account.
