Explode : MAKEASS.EXE and DISASS.EXE
The programm
MAKEASS.EXE convert a BINFILE in a Source-Textfile
with lines like the
follow:
FCB $86,$01,$B7,$10,$3D,8E,$00,$FF $E000-$E007
Any
assembler convert this Source-Textfile in a Binfile to compare
with the
original BINFILE.
The disassembler DISASS.EXE opens the original
BINFILE and the user
can see the binary and disassembled code.
With F8
the user can save a marked block and
insert in the Source-Textfile created
with MAKEASS.EXE.
Step by step the user can disassembled all the routines
of the
orginal BINFILE.
The user must decide if the code is a program, a
text or a datatable.
The reassambled code with a compare (FC file compare)
is the security.

TCP-IP with small MICROCONTROLLER
8-Bit MICROCONTROLLER sent E-MAILS
TCP.ZIP (27.751
Bytes) PPP.EXE + SCAN.EXE
At the moment I´m just working on a
project in which I try to
send an e-mail with a small 8-Bit
microcontroller
( ex. 68HC11, 80C51).
It should contain the status of
the periphericals in text
format, like:
INPUT 1 = OFF
INPUT 2 =
ON
TEMPERATUR 1 = 23,6 GRAD
TEMPERATUR 2 = 18,5 GRAD
To reach
this object I following the steps stated below:
1) I send an e-mail
from my PC under Windows.
2) I connect the second PC between COM2 and
the Modem.
3) I tracked the data stream (PPP, LCP, IP, TCP, UDP
)
with my mailtool (with my own program in 'C++')
and the second PC and
analyzed it.
4) My program PPP.EXE receives the data on
COM2 and
COM1 and save it in ASCII-HEX-Format
5) I scan the data with my program
SCAN.EXE and filter out
the various protocols and save them as formatted
text.
6) I use various RFCs as guideline.
7) I would write the
program on micro in assembler with
a code under 64K, otherwise I use
banking.
MY QUESTION:
Is there someone else who is working on the
same
problem ???
