Google for "netcat manual"...

Ah... So this talks about netcat for Windows NT (clear indicated by nc.exe), but not for UNIX. I'd rather believe the man page and the output of nc -h than some random google'd website.
There is no -L option. Neither in /usr/bin/nc nor in /opt/local/bin/nc nor in nc on the Linux boxes I have access. Since such an parameter isn't mentioned anywhere, it doesn't seem to exist in netcat for UNIX. I can't tell if it exists in a Windows version.
Fortunately there's more than one netcat out there ... :) I've always wanted to submit a port for GNU Netcat, but never got around to it. You can always install GNU netcat from source. I think I remember that it's a pretty straightforward compile.
