* <li>If the required pathname parameter is missing, then reply with 501 and terminate</li> | |
* <li>If the pathname parameter does not specify an existing directory, then reply with 550 and terminate</li> | |
* <li>If the current user does not have execute access to the directory, then reply with 550 and terminate</li> | |
* <li>Otherwise, reply with 250 and change the current directory stored in the session</li> | |

* The supplied pathname may be absolute or relative to the current directory. | |
