//! Protection Buffer Size
//!
//! To protect the data channel as well, the PBSZ command, followed by the PROT command
//! sequence, MUST be used. The PBSZ (protection buffer size) command, as detailed
//! in [RFC-2228], is compulsory prior to any PROT command.
//!
//! For FTP-TLS, which appears to the FTP application as a streaming protection mechanism, this
//! is not required. Thus, the PBSZ command MUST still be issued, but must have a parameter
//! of '0' to indicate that no buffering is taking place and the data connection should
//! not be encapsulated.
