Device A <------> Device B using a serial cable. I want to monitor the traffic between the two devices. I have Serial Port Monitor, Serial Port Terminal and Virtual Serial Port components.
I have connected Device A to COM6 and Deivce B to COM7. I have run Serial Port Monitor and opened both COM6 and COM7 .. but I cannot connect the input from COM6 to the output of COM7 and vice versa.
I tried using Virtual Serial port to create a pair from COM6 and COM7 which it did .. and it did connect the two together, but it also connected their inputs so they can talk internally but not externally.
Is there a way using any of the Eltima components to connect COM6 to COM7?
Sorry for so overdue reply.
In fact, you can use Eltima Software products in order to monitor the communication between two serial devices that are connected to the same computer (even with no serial cable used).
For the specified purpose we will need to use Serial Splitter in pair with Serial Port Monitor.
In order to be able to monitor the data flow between two devices, they should both be connected to the computer via COM ports. If your computer doesn't have two COM ports, USB to COM adapters can be used instead.
With Serial Splitter you'll be able to redirect all serial traffic from one real port (where your first device is connected) to the second one (where the second serial device is plugged in accordingly). This will allow two serial devices connected to the same computer to communicate exactly as is they were connected with a serial cable.
After that you'll merely have to install Serial Port Monitor to monitor one of the real ports. Please note, that you don't need to monitor two real ports simultaneously. Monitoring only one serial port will suffice as, obviously, if the devices are connected via a serial cable (or all the data is just redirected from one real serial port to the other as I described above), the data written to one serial port will be received unchanged on the other and vice versa.
