     Release Notes of U-1496 series modem,  version 6.17 (09/12/96)

     ===============================================================





Fixed the bugs:

---------------

1. In dial backup mode,	leased line is broken and dial-up line is up.

   For some reason dial-up line	is broken too, then the	modem will not

   restore to leased line or either retry dial-up line.

2. Null	character append after some display messages.

3. Not display dialing message when in redialing.

4. Synchronous connection sometimes randomly disconnect.

5. Answer tone can not be detected when	the line go through some specific

   PABX	to outside line.

6. Pin 140,141 too sensitive, add debunce timer.

7. Fax can not work if s35.1=1.

8. When	the Class 2.0 modem is initialized (AT+FCLASS=2.0) for fax/data

   adaptive answer (AT+FAA=1). The incoming data call is not reported

   properly, the first response	should be +FDM.
