Hmm that's odd, it worked here. I'm still using ioFTPD beta-5.8.5r here, which version are you using?
Code:
CWD /REQS
250- -------------------------------------------------------------------------
250- ID# | Owner | Request
250- -------------------------------------------------------------------------
250-| There are currently no requests. |
250-'------------------------------------------------------------------------'
250- '-----( Type 'SITE REQUEST <title>' to make a request. )-----'
250 CWD command successful.
