Monitor for FTP Put Command successful

[entrack]

226	Closing data connection.

Currently I am programatically monitoring for a successful completion of the Put command with a return code of 226 (Requested file action successful ).
But I an mow connection to a server that is instead sending message '250 STOR'. My question is if I monitor for '250 STOR' in the log will that always signify successful completion of the PUT command?
