FTPS problems

I've been trying FTPS with latest curl. Don't know if the order
of checking the schemes in url.c has anything to do with my
problems, but it looks suspicious. Shouldn't "FTPS" be checked
before "FTP" (since strncasecmp is used).

A friend of mine clams to have a FTPS enabled server running,
but I can't get it to work.

Tried with -2 and -3 and w/o --ftp-ssl with similar results. This is a trace
from tethereal:

(my IP = 10.0.0.6).

I can get in with SSHv2 (sftp and scp) okay, but I honestly doubt
the ftp-server has SSL. An ideas?
