KNOWN LIMITATIONS

   Operating System Support:

      This release no longer supports Windows NT 3.XX.

   Installation/User Interface:

      Within the wizard mode, if invalid input has been entered and 
      back button is pressed, an error message might appear indicating 
      that the input is invalid. Valid input needs to be entered 
      to be able to go back.

   PortAssist Viewer:

      The PortAssist Viewer shows a Line Speed and Configured Baud 
      Rate of zero for the SYNC/570 if the link is externally clocked.
      If the link is internally clocked both values show the 
      Configured Baud Rate. The SYNC/570 does not calculate the Line 
      Speed.

      PortAssist Viewer shows a protocol of SDLC for QLLC SNA 
      links.

      Use the raw data for problem diagnosis.

   RAS Adapters:

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

      When configuring dial-up modem service for a line, all modems on 
      the line should be configured since incoming calls may be 
      assigned to any channel.

      On ISDN Trunks, the following rules are applied to modem dial 
      strings:

         A comma (delay) in the first or second position is allowed.
         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).

   SYNC Adapters:

      For PPP links, both sides of a connection must disconnect before
      they can be reconnected.

      When using the SDLC interface, the maximum BTU (Basic 
      Transmission Unit) is limited to 521 bytes. This is a known 
      limitation of the IBM SDLC link service provided in SNA Server. 
      See the Microsoft SNA article, "Maximum BTU Limit for Dumb 
      SDLC Interface" for more information.

   AccelePort Xp Adapters:

      RTS toggle is not supported.

      BUG FIXES
   
         The DigiView trace feature sometimes identified ISDN SETUP 
           packets as UI frames on Basic Rate (BRI) lines.
         A problem was fixed where service messages brought down the 
           PRI line on some National ISDN switches.
         Problems relating to the failure to establish ISDN modem 
           connections were fixed.

           status information on line 1 was being misinterpreted as 
           status information for line 2.
         Finally, there was a bug that was fixed that might have 
           potentially caused problems with adapters that have 
           interrupts activated. No such problems have been reported 
           to date.
