SerialSniffer

is a windows shareware to visualize data, which are exchanged over the serial ports (i.e. RS232 or RS422).

SerialSniffer gives you the possibility

to have a deep view inside the data. The data stream, which is exchange on the serial ports, is visualized by SerialSniffer. You also can determine which data comes from which port.
to log the data stream
to tunnel the serial port through the network
to exchange dedicated data parts from the data stream
to search for seldom data
to open a terminal dialog
to use symbols instead of raw data

SerialSniffer is very easy to use

Simply choose the type of connection (serial, network or virtual serial port), the parameters (i.e. baud rate) and open the connection.
Not only the standard baud rates (like 9600 baud) but also user defined baud rates can be used. It is also possible to translate between different baud rates, as both comports can be configured independently.

Comport names up to “Com256:” are supported to use SerialSniffer on systems with a lot of serial ports (provided by additional adapters, IRDA, Bluetooth etc).

The complete configuration will be stored automatically on closing the application. The user can also store it in customized files to re-load it for recurrently tasks.

How to connect SerialSniffer with other hardware

SerialSniffer does not change anything on the pinning of the ports. You will need exactly the same cables to connect the port with another device, as if any other application (instead of SerialSniffer) will use the port.

Most common, you will have to use a null modem cable (a cable with RX and TX crossed) to connect two PCs with each other, in opposite to use a straight cable to connect a PC with an external device.

In case, the communication will not work, try to use another cable type. In most cases, a permutation of RX and TX is the reason for malfunctions. We have never heard about a hardware defect, which results from crossed cables. It is also possible, that one part of the communication is using hardware or software handshaking. On encountering difficulties, you should try to switch the handshaking off.

Modul A

SerialRecorder

The SerialRecorder gives you the possibility to store the data stream of an external device in a file and do a playback later. This can be compared with using a traditional tape system for the data. The timeline (including the pause between data blocks) will also be stored in the file.

Modul B

VirtualSerialPort

In most cases, an external device communicates with an application running on the PC. To get SerialSniffer inside the communication channel, the easiest way is to use the virtual serial port provided by SerialSniffer to which the existing application can connect. Therefore, only one physical serial port is needed.
