Hi All! how are you?
 -= Changes between the Supra 288 1.44-15 and the 1.440-16 ROM Code =-
1)  On products with 2 character LED displays, the "RJ" and "TJ"
    indications were being handled as error indications that 
    reset the display cycle.  They are now normal indications,
    they will appear in place of the "LP" indication if needed
    during a display cycle.
2)  On models with 2 character LED displays, the "RE" error
     indication will appear when a LAPM frame is received with
     a protocol violation.  On models with LED displays, the
     message "RX ERROR" will be displayed.
3)  The maximum duration of a retrain or rate renegotiation
    sequence has been limited to 90 seconds, including any
    retries.  At the end of 90 seconds a hangup will be initiated.
    NOTE: Some other modem brands will finish a retrain and 
          immediately start a new one.  This counts as two
          retrains, each of which is given 90 seconds to finish.
7)  LAP-M was modified to improve performance.
8)  On models with LCD displays in display debug mode (S194.3=1),
    the display will show "TX RNR" whenever the local modem 
    enters own busy state and transmits a LAPM RNR frame.  The
    display will show "RX RNR" whenever the local modem receives
    a LAPM RNR frame indicating the remote modem is in busy state.
9)  After a disconnect the %Q2 report will print the following
    messages based on the disconnect reason given in S86.
            S86   %Q2 disconnect reason
