   --------------
 
   The LPC1766-STK board has two serial connectors.  One, RS232_0, connects to
-  the LPC1766 USART0.  This is the DB-9 connector next to the power connector.

+  Simple UART1 is the more flexible UART and since the needs for a serial
+  console are minimal, the more minimal UART0/RS232_0 is used for the NuttX
   system console.  Of course, this can be changed by editting the NuttX
   configuration file as discussed below.
 
+  The serial console is configured as follows (57600 8N1):
+
+    BAUD: 57600
+    Number of Bits: 8
+    Parity: None
+    Stop bits: 1
+
+  You will need to connect a monitor program (Hyperterminal, Tera Term,
+  minicom, whatever) to UART0/RS232_0 and configure the serial port as
+  shown above.
+
+  NOTE: The ostest example works fine at 115200, but the other configurations
+  have problems at that rate (probably because they use the interrupt driven
+  serial driver).  Other LPC17xx boards with the same clocking will run at
+  115200.
