It sounds like your difficulty is with multi-line responses. Here's what they look like

Code:

123-ABC
Foo
Bar
 789 Baz
123 XYZ

The response line begins with the number as usual, but next comes a hyphen - not a space.
Subsequent lines follow. If any of them begin with a number then the line should be indented with whitespace.
The final line is the status code, a space, and then arbitrary text.

So your LIST should look like

Code:

NNN-Directory listing of /foo/bar
One
Two
Three
NNN End of listing

FEAT is defined a little more precisely:

Code:

211-Foo
 feature
 feature parameters
 feature parameters
211 End

A 211 status code with any message,
Lines beginning with a space. First "word" is the feature and more information may follow (after a space),
A "211 End"

See also: RFC 959 (4.1.3 for LIST; 4.2 for multi-line responses), RFC 2389 (FEAT), RFC 3659 (FTP extensions).
