--crlf (Use CRLF as EOL)

protocols that use CRLF for end-of-line.
--help (Help screen)
Displays a short help screen with common options and parameters,
and then exits.
--recv-only (Only receive data)
If this option is passed, Ncat will only receive data and will
not try to send anything.
--send-only (Only send data)
If this option is passed, then Ncat will only send data and will
ignore anything received. This option also causes Ncat to close the
network connection and terminate after EOF is received on standard
--no-shutdown (Do not shutdown into half-duplex mode)
If this option is passed, Ncat will not invoke shutdown on a
socket after seeing EOF on stdin. This is provided for
backward-compatibility with OpenBSD netcat, which exhibits this
behavior when executed with its '-d' option.
--telnet (Answer Telnet negotiations)
Handle DO/DONT WILL/WONT Telnet negotiations. This makes it
possible to script Telnet sessions with Ncat.
--version (Display version)
Displays the Ncat version number and exits.
