+/*------------------------------------------------------------------------
+ hello.c - This is a simple program designed to operate on basic MCS51
+   hardware at 11.0592Mhz.  It sets up the baudrate to 9600 and responds
+   to simple ascii commands on the serial port.
+
+   Its intended to be a simple example for SDCC and ucSim.
+   The redirection of the simluated serial port to a TCP port
+   is cool, try this:
+   Try: 
+   1.) type>s51 -k 5678 hi.ihx
+   2.) (Now telnet to 127.0.0.1 Port 5678)
+   3.) At the s51 prompt, type: run
+   4.) At the telnet prompt, type in a few keys followed by CR
+   5.) You should see this program send back what you typed.
