Is IOS FTP server rfc959 compliant?

I'm having some problems getting a Siemens application and a Cisco IOS FTP server communicating. I think it may be because neither has implemented RFC959 correctly. My question to you is about the Cisco IOS server.

I'm using the Cisco IOS server i.e.:

ftp-server enable

ftp-server topdir <whatever>

I notice that if I use the Microsoft DOS command line FTP client, and issue an 'ls' command to the Cisco IOS FTP server then, among other commands, the relevant FTP command sent by DOS is 'NLST'. According to RFC959 this should send a simple stream of filenames separated by CR/LF and no other information. However DOS displays the fully formatted results i.e. with attributes, dates, file size etc. This is more like what I'd expect from the 'LIST' FTP command.

So the question is, does the Cisco IOS FTP server comply with RFC959 NLST command? Or am I interpreting things wrong (I haven't done a full protocol analysis yet)?

IOS is (C1841-BROADBAND-M), Version 12.4(1a).
