Enabled BUSYBOX_CONFIG_NC_110_COMPAT (and not _SERVER or _EXTRA) and all it got me was "nc: NO OPT l!", even when attempting to use it for TCP.  I've fallen back to building and using socat for my UDP needs, but that's not ideal.


root at webserver:~# nc --help
BusyBox v1.27.2 () multi-call binary.

Usage: nc [OPTIONS] HOST PORT  - connect

	-e PROG	Run PROG after connect (must be last)
	-p PORT	Local port
	-s ADDR	Local address
	-w SEC	Timeout for connects and final net reads
	-n	Don't do DNS resolution
	-u	UDP mode
	-v	Verbose
root at webserver:~# nc -l -u 172.29.7.1 15
nc: NO OPT l!
root at webserver:~# nc -u 172.29.7.1 15
nc: NO OPT l!
root at webserver:~# nc -u
nc: NO OPT l!
root at webserver:~# nc
nc: NO OPT l!
root at webserver:~# nc 172.29.7.1 15
nc: NO OPT l!


All told, a little antisocial of it.
