to demonstrate the viability of communications at 57600 baud.  A 57600 baud PC
client is included: client/demo.exe.
r.a ......... A non-trivial sample assembly program.
r.hex ....... Its Intel Hex listing.
entries...... A list of entry points to be used with r.hex.
r.s ......... The source derived from the Intel Hex listing.

                                  collection software in the data directory.
           micronet.doc ......... Command reference for MicroNet.
           console.c console.h .. IBM AT-compatible, VGA-compatible console
                                  routines.  Used with serial.c
           serial.c serial.exe .. Diagnostic command/communications monitor
                                  for MicroNet.
           serial.doc ........... User reference for serial.exe.

CRC: 8051/crc
An 8051 8-bit CRC demo.  Redefines Intel Hex Format so that it uses 8-bit
CRC's, and performs a hex dump of addresses 0 to 2000h in the code space.
   crc.doc ... A brief outline of the crc demo.
   8052.h .... Include file for crc.asm ... a copy of 8051/kernel/8052.h
   crc.asm ... A program that prints out an Intel Hex Format dump of addresses
               0 to 1fffh in code space.  However, instead of calculating check
               sums by adding all the bytes on each line, as is done with Intel
               Hex Format, an 8-bit CRC is produced.
               This also demonstrates communications at 57600 baud using 9 bit
               addressing.  The serial address in this program is ':'.  Every
               key except 's' is echoed.  A hex dump, as described above, is
               send when 's' is received.  Responses will only be produced
               when the address received exactly matches ':'.
   crc.hex ... The assembled CRC demo.
   crc.c ..... C source for a filter that verifies Intel Hex Format CRC's.
   sample.hex  A sample Intel Hex Format file redefined to use 8-bit CRC's.
               If crc.c is compiled into an executable (named crc), then
               running crc <sample.hex will verify sample.hex.  This file was
               generated by crc.asm.
