ftp = chilkat.CkFtp2()

#  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
if (success != True):
    print ftp.lastErrorText()
    sys.exit()

ftp.put_Hostname("ftp.chilkatsoft.com")
ftp.put_Username("mylogin")
ftp.put_Password("mypassword")

#  Connect and login to the FTP server.
success = ftp.Connect()
if (success != True):
    print ftp.lastErrorText()
    sys.exit()

#  ...

#  At any point in an FTP session, the IsConnected property
#  can be checked to determine if the component has remained
#  connected to the FTP server.
if (ftp.get_IsConnected() == True):
    print "Connected!"
else:
    print "Not connected!"
