  4) WAN Miniport Driver
  5) ISDN COM-Port Driver
  6) cFOS Driver from AOL and CompuServe

1) ISDN Characteristics

   - Common ISDN API (CAPI) version 2.0 Driver
   - Wan Miniport Driver (32 Bit)
   - COM Port Driver (16 Bit)

   D-Channel Protocols Supported
   - Europe :   Euro-ISDN (DSS1)
   - USA:       NI-1, 5ESS, DMS-100
   - Japan:     INS64
   - Australia: TPH1962

   B-Channel Protocols Supported
   - Bit Transparent
   - HDLC Transparent
   - ISO 7776 (X.75 SLP)
   - T.90 NL with compatibility T.70 NL
   - ISO 8208 (X.25 DTE-DTE) 
   - X.31
   - T.30 for FAX group 3
   - T.30 for FAX group 3 with extensions
   - V.110 asynchronous operation
     (auto detect 9600 Bit/s, 19200 Bit/s, 38400 Bit/s)
   - V.110 synchronous operation (56 kBit/s)
   - V.120 asynchronous mode

2) Setup

   Using CAPI protocols from other vendors:

   Setup will bind a CAPI20 protocol to the ISDN board driver
   automatically. If you like to use a different CAPI protocol
   you have to launch setup with the command line option +A .
   In this case you are responsible for binding a CAPI protocol
   on top of the board driver yourself. If no CAPI protocol is
   present, the board driver will not be loaded.

3) CAPI2.0 driver

   The Windows95 CAPI 2.0 Interface supports 16 bit
   programs (CAPI20.DLL), 32 bit programs (CAPI2032.DLL)
   and device drivers (vcapid.vxd). The DOS interface
   (INT F1) is not supported in this version.

4) WAN Miniport driver

   All board specific configuration items must be adjusted via
   the extra property pages provided by the ISDN board

   Following features are included with this version (1.11):

   - connect as a remote node to a RAS server (either
     Windows NT or Windows 95)
   - allow dial in as a Windows 95 RAS server
   - Since Microsoft supports only one ISDN connection at
     a time under Windows 95 this driver it is not possible to
     connect to more than one destination concurrently.
   - Microsoft supports the dial-up to a RAS server with
     PPP-Multilink support making use of 2 b-channels for one
     logical connection. This has been tested.
   - No support of multiple ISDN adapters; due to the above
     mentioned restrictions, this is not very important, anyway. 
   - Support of "Accepted MSN" to specify calls to which
     MSN should be accepted.
   - Support of "Own MSN" to specify which MSN is calling
     on generating a call.
   - Support of different B-channel protocols. Choose between
     HDLC-transparent (default) or X.75. This setting will be
     used for all ISDN connections over the wan miniport.

   Known Problems:

   - The ISDN Accelerator Pack Version 1.1 seems to have a
     severe bug concerning the IPX protocol. The actual
     throughput with IPX on a file copy towards the remote
     system is very close to 60 kBit/sec, while the netto
     throughput is less than 40 kBit/sec. Since the same
     behaviour can be observed with already certified drivers
     from competitors and does not show up with other
     protocols (IP, Netbeui) we believe that it is caused by a
     bug in the ISDN Accelerator Pack.

5) ISDN COM-Port driver

   The COM-Port driver included in this version supports
   all 16-bit applications that use the Windows-API
   to access COM-Ports (e.g. T-Online, CompuServe CIS
   AOL or Telix for Windows). 

   The configuration of the ISDN ports is done in the
   Windows 95 control panel with the option "Dynalink ISDN-Port". 

   For further information about the driver please consult
   the file iCom3x.txt which is placed in the installation
   directory of the ISDN card.

6) cFOS Driver from AOL and CompuServe

   For stable use of COM-Port drivers bundled with AOL and
   CompuServe access Software the user has to adjust a few
   parameters. Further information can be found in the file
   aolcmpen.txt on Disk 2 of ISDN Driver.
