How to use slsnif

Hi all ,

I have a device to which Im communicating it with USB-Serial IC.
its device number is /dev/ttyUSB0.

There is only one port through which Im communicating. I want to use slsnif to monitor the data transfer between the device and my application.
But when I run the slsnif --->

slsnif -l log.txt -n /dev/ttyUSB0 
Started logging data into file 'log.txt'.
Opened pty: /dev/ttyp0
Saved name of the pty opened into file '/tmp/slsnif_pty'.
Opened port: /dev/ttyUSB0
Baudrate is set to 9600 baud (default).

But when I try to communicate the device with the application . The application was not able to communicate.

Can anybody help me how to monitor the serial device.

Thanks and Regards

Same exact problem here. I'm using the same command, same ports, and I have the same error. My application is using RxtxSerial (java). I'm hoping someone knows of a serial sniffer that will work with USB-to-serial kernel drivers such as CP210x driver. Thanks.
