Section APPENDIX II says:
CWD /usr/dm 200 directory changed to /usr/dm ... CWD overrainbow 431 No such directory
It should say:
CWD /usr/dm 250 directory changed to /usr/dm ... CWD overrainbow 550 No such directory
Reply codes in the examples are not conform to the specification :
200 is not a valid code for CWD. It should be 250 (Requested file action okay, completed).
431 is not a valid code for CWD and is not defined in the RFC. It should be 550 (Requested file action not taken).
