Section 5.4 says:
CDUP 200 500, 501, 502, 421, 530, 550
It should say:
CDUP 250 500, 501, 502, 421, 530, 550
Notes:
The reply codes for CDUP are supposed to be identical to those of CWD according to Appendix II - Reply Codes. Thus, the proper return code for a successful CDUP should be 250 - Requested file action okay, not 200 - Command okay.
