FINISHED?
Goals: - build free serial line sniffer
- mark which data were transmited and which received to
easily decompose transmision protocol

- I have modified a little the hardware so transmision on one
line pulls high CTS line on sniffing device. Now I have to write some
software (probably in delphi to save time) that will correctly
recognise direction. First version works
preety well, but there is no "real" hex editor, just simple TextGrid
that can't even set text/background color in single cell :( I will
probably have to play with modyfing component...

| I see that it is not easy to build rs
sniffer with data direction mark using PC as hardware. It is almost
impossible when it should watch asynchronous transmision. Besides my laptop
have only one serial port, but also have one parallel port. So all signs on
earth and heaven tells to bulid simple hardware that will sniff asynchronous serial transmission
and pass the result to parallel port. That will also help writing
platform-independent software. |
