how can find specifiction of a unknown network X
hello how can find a specifiction of a protocol xxx? such as baud rate , data bits , parity , stop bit , flow control ... thank you very much
I have no idea what specification you're looking for, but I suppose you could try starting with an internet search for it?
Those are mostly properties of an asynchronous serial line; a protocol running on an asynchronous serial line might specify that serial line parameters, but it probably also specifies a lot more.
What is the name of the protocol for which you're looking?
