set either of these variables to "nc". Input and output can be
switched independently.
+We use an environment variable 'ncip' to set the IP address and the
+port of the destination. The format is <ip_addr>:<port>. If <port> is
+omitted, the value of 6666 is used. If the env var doesn't exist, the
+broadcast address and port 6666 are used. If it is set to an IP
+address of 0 (or 0.0.0.0) then no messages are sent to the network.
+
On the host side, please use this script to access the console:
+++++++++++++++++++++++++++++++++++++++++++
stty icanon echo intr ^C
+++++++++++++++++++++++++++++++++++++++++++
+It turned out that 'netcat' couldn't be used to listen to broadcast
+packets. We developed our own tool 'ncb' (see tools directory) that
+listens to broadcast packets on a given port and dumps them to the
+standard output. use it as follows:
+
++++++++++++++++++++++++++++++++++++++++++++
+#! /bin/bash
+
+stty icanon echo intr ^T
+./ncb &
+nc -u mpc5200 6666
+stty icanon echo intr ^C
+kill 0
++++++++++++++++++++++++++++++++++++++++++++
+
For Linux, the network-based console needs special configuration.
Minimally, the host IP address needs to be specified. This can be
done either via the kernel command line, or by passing parameters
