Command 0x23 - is it implemented?

The copy of the protocol specification that I have notes that the command to set the receive mode to STRUCT (0x23) isn't implemented yet. I'm running firmware v5.9 and when I send the command sequence I receive a 0x21 (CMDOK). However the only data that I then get back is 0x82 which is the code for CMDERROR.
I'm running on FC2 and I'm playing around with the USB-UIRT.pm module that comes with Misterhouse.
While I'm at it, is there an uptodate version of the spec? I note that the same spec doesn't mention the SET_MODE_RAW (0x24) that I saw John refer to in a posting from 2003 (or maybe even 2002).
