Software Image P/N 40001907_D

Enhancements

   V.90 modem support.

   Update via network control panel.

   Implemented ATI9.

Bug Fixes

   After doing properties on a RAS adapter, network control panel 
   states there has been changes and that you must reboot, even if 
   you clicked cancel.

   ISDN Tapi devices (B Channels) are not addressed correctly, and
   do not show up in RAS setup from NCPA.

   BRI 5ESS and DMS100 switch types do not work properly.  Only
   use NI-1 switch type on DataFire RAS B4U.

   Auto-detection of Digi RAS 56K Modem by modem control panel does
   not work.

   Clients using V.90/K56Flex modems should issue AT+MS=56 to
   connect using K56Flex for best speed. V.90 modems will be
   connected at V.34 rates.

   Clearing statistics in Portassist Viewer works.

   Advanced ISDN settings now display properly under Information
   window.

   Serial port names cannot be duplicated.

   Software flow control has been fixed on serial ports.

   Fixed ATI7.

   ISDN numbers must not contain any non-numeric characters
   (e.g. "-").

Known Problems

   Resetting a modem causes the settings stored in NVRAM for other
   modems to reset.

   Caller ID data is currently ignored.

   Channelized T1 Wink Digits are currently ignored.

   On Channelized T1 Wink Start Trunks without dial tone
   supervision, modems must be initialized with ATX3 for dial
   out.

   Currently, modems are not automatically assigned to open serial
   ports when calls are received. They are assigned based on the
   timeslot of the call. Therefore, unless all the serial ports to
   the board are open, it is possible a call will not be answered.

   On ISDN Trunks, the following rules are applied to modem dial
   strings:
      a) A comma (delay) in the first or second position is
         allowed.
      b) then the first non-numeric character terminates the dial
         string (e.g. 9,12345678 is a valid dial string and
         9,1,234-5678 is not).

   BRI and PRI adapters do not function properly under RAS when
   installed in the same machine.  This is a known limitation of
   NT 4.0.
