snooper - serial line snooping tool
The tool is for snooping communication between two devices
that communicate with RS232C serial line.
Machine configuration
There are 3 machines/modems to take part in the configuration.
We will denote those machines as follows:
partyA a computer
partyB computer/modem/digi-cam/whatever
console The computer you are using to snoop
the communication between A and B.
Say, you would like to snoop the following configuration.
partyA ---cableAB--- partyB
In that case you should connect "console" between partyA and
cableAB, as follows:
partyA ---cableX--- console ---cableAB--- party B
cableX must be cross-cable (a cable to connect two computers).
Command-line options
% snooper [-options] dev0 dev1
-bBAUD specifies baud rate.
-u don't use uucp locking (questionable option)
dev0 name of serial device 0.
dev1 name of serial device 1.
