AT%Q2     Data Transfer Stats (Current call or last call)
           On ALL Connections these items are reported:

           On V.42bis (BTLZ) Connections these items are also reported:

                BTLZ string length   =
                Transmit Compression =(enabled/disabled)
                Receive Compression  =(enabled/disabled)

            The %Q2 status screen now includes the number of octets
            transmitted and received in LAPM I frames.  It also 
            includes the number of I frames retransmitted due to SREJ 
            and REJ frames being received and the number of I frames 
            retransmitted due to timer T401 expiring.

            REJ frames cause the retransmission of an I frame and any
            I frames that were transmitted after that I frame.  The 
            number of I frames retransmitted due to REJ frames is 
            usually more than the number of REJ frames received.

            SREJ frames cause the retransmission of a single I frame, 
            any I frames transmitted after the rejected I frame are 
            not retransmitted.  The number of I frames retransmitted 
            due to SREJ is usually equal to the number of SREJ 
            received.

            The number of I frames retransmitted by REJ and SREJ 
            frames may be lower than expected if acknowledgements of 
            the requested I frame arrive after the receipt of the 
            REJ/SREJ for that I frame and prior to the retransmission 
            of the I frames.  This may happen if I frames are 
            retransmitted due to the expiration of T401 and a REJ/SREJ 
            is received for the original transmission of the I frames.
