+The source / listening port can be configured separately by setting
+the 'ncinport' environment variable and the destination port can be
+configured by setting the 'ncoutport' environment variable.
+
+For example, if your server IP is 192.168.1.1, you could use:
+
+ => setenv nc 'setenv stdout nc;setenv stdin nc'
+ => setenv ncip 192.168.1.1
+ => saveenv
+ => run nc
