7/31/97 Release Notes

1. Added S30 register to enable/disable feature upgrades.
2. New DSP code improves V.34 performance.
3. Corrected invalid data in ATI6 and ATI11 screens during x2 and
   V.34
4. Corrected V.34 training in presence of high echo.
5. Corrected DTMF tone generation.

Please note, if the Courier modem is updated to this new code but X2
has not been enabled, S register 30 will need to be set to a value of
1 prior to dialing the upgrade line to enable X2 (see #1 above). This
register cannot be written to NVRAM. If your modem already has X2
enabled (check ATI7) or if you do not wish to purchase an X2 upgrade,
you may disregard this notice.
