From this post we know that

There are two common modes for transferring files via FTP, ascii and binary

It is about media connection. But also there is a control connection, which has some info like IP addresses and so on.
Does the info inside control connection have binary or textual format?

The FTP control connection is text. It's mostly 4-character all-caps command mnemonics and occasional IP addresses (in dotted-decimal ASCII) and port numbers (in ASCII numerals). And of course path and file names in text.

    It's not just that it's text – but it's also specifically defined to be NVT-ASCII text with CRLF line endings, so it's exactly the same as "ASCII" data transfer mode.
