Version 3.03


1. AON sample rate changed from 7200 s/s to 11320 s/s.

2. %RO command added to control modem behavior on line  distortion.  Old
   versions unconditionally hangup on rx signal change >  6db  and  echo
   correlator values > 700 threshold (AT&T workaround to detect  carrier
   loss). %RO command adds some flexibility - modem can either hangup or
   try to retrain.

   Syntax:      AT%ROn, where n either 0, 1, 2, 3:

        0 - unconditionally hangup on bad correlator and signal change
        1 - unconditionally hangup on  signal  change;  retrain  on  bad
            correlator
        2 - unconditionally hangup on bad correlator; retrain on  signal
            change
        3 - retrain on both signal change and bad correlator

3. Fixed bugs in speaker control:

        - ATD <CR>, speaker was always disabled
        - ATM2, speaker turned off upon retrain

4. Fax mode: fixed problems with  fax  reception.  AT&T  workaround  #22
   (V.29 and V.27ter startup problems on noisy lines) doesn't appear  to
   work correctly. V.21 ch2 carrier detection didn't  work  properly  on
   noisy lines. We have to change mode (page to  HDLC  and  back)  every
   time we expect remote to switch from one to another, esp.  :  on  the
   end of page, on FTT, on CFR.

Version 3.04


1. Fixed a bug in Ver. 3.03, Class 2 fax receive mode  if  more  than  1
   page in the fax message and there's no retrain between the pages (ie,
   MPS, MCF, next page).
