The only difference between Digitrace and Hyper Terminal/Putty/Hercules etc is that it is date and time stamped to help with finding the data quickly.

Connect a TTY cable onto the monitor port of the RPTB/BPTU card and set your capture software to 9600 baud rate, 8 bits, No Parity,1 stop bit and set it to capture the data to a text file.
If you are unsure what you see then send it to one of us to decipher for you.
Tell us the DID number you are dialing and the number you are dialing in from.
