Uni.X to Uni.X .NETworking - Sending 1 Byte Instant Messages With a
Check-Sum

Given the 160 bit Uni.X to Uni.X .NETworking message format for the NOP
Protocol:

PP=00

SSDD.SSDD.SSSSDDDD.SSSDDD.LLBBBBBBBB
SSSSSSSDDDDDDD.SD.DDSS.SSSSSSDDDDDD
SDSDGTTT.00SSSDDD.CCCCCCCCCCCCCCCC
SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD

LL=01

BBBBBBBB is the 1 byte of data and the Check-Sum CCCCCCCCCCCCCCCC
is still encoded.

Assuming: 20+32+12

2 - Fixed 01  <<<<< From half of the First 4 Bits
2 - Fixed 01
4 - Now
3 - Fixed 000
7 - Now
2 - Fixed 11
<<<< 32-bits >>>>
1 - Fixed 0
6 - Fixed 000000
1 - Fixed 0
1 - Fixed 1
3 - Now

Note: There is no 16-bit extended addressing that comes from the
Socket-Abstraction
code-bloat. The 160-bits are a self-contained message. Each time you hit a
key, a message
is sent. The byte is 8 bits. To deliver that byte end-to-end with some
reliability takes
about twenty times more bits. If you want to talk and type, that is
supported and it does
not add to the number of bits required.

By the way, the messages have not changed in 30+ years.

"Nearly all problems converting code to 64 bit can be summarized in one
simple rule: Do not assume that long, int, and pointers have the same size.
Any code violating this rule will cause various subtle problems in your
application when running under an LP64 data model that will be difficult to
track down."

Also, by the way, are you aware of what THE Big Lie Society never wants you
to see ?

The C+@ Programming Language
Jim Fleming
C+@ (pronounced "cat"), an object-oriented language out of AT&T Bell Labs,
has the syntax of C and the power of Smalltalk. Unlike C++, however, C+@
includes a library of more than 350 classes.
