            Eicon Technology's SDLC Driver For NetWare For SAA
            ==================================================


INTRODUCTION
============
Eicon Technology's SDLC Driver for NetWare for SAA permits an EiconCard to 
be used as an SDLC adapter in NetWare for SAA V1.2 and later. The EiconCard
with its SDLC software is used in a manner similar to the NetWare for SAA 
Synchronous Adapter. A single command is used to configure, start, and load 
the SDLC driver module.



Supported EiconCards
====================
These EiconCards are supported by the SDLC Driver:
    EiconCard/PC
    EiconCard HSI/PC
    EiconCard/MC
    EiconCard HSI/MC

Note:
When installing a Micro Channel EiconCard, ignore any references to the
installation of Eicon Technology software in the EiconCard Installation
Guide.



THE ECSDLC NLM
==============
The Eicon Technology ECSDLC NetWare Loadable Module (NLM) controls the 
EiconCard SDLC interface to NetWare for SAA. The NetWare LOAD and UNLOAD 
commands are used to respectively activate and deactivate the SDLC support.

Note:
The NetWare for SAA commands CSLOAD and CSUNLOAD are required to create and
remove SDLC connections. Please consult the Novell documentation for details.



INSTALLING THE SDLC SUPPORT
===========================
The Installation disk contains two sub-directories, EICON and SYSTEM. The 
contents of these sub-directories must be copied to sub-directories of the 
same name on the file server. The SYSTEM sub-directory already exists on 
the file server. The EICON sub-directory must usually be created.

Perform the installation as follows:

    1. Login to the desired file server as Supervisor.

    2. Make the network drive current (e.g., F:).

    3. Make the SYS volume current (e.g., CD SYS:).

    4. Make the root directory current (e.g., CD \).

    5. If it does not already exist, Create the EICON sub-directory
       (e.g., MD EICON).

    6. Copy the contents of the EICON sub-directory on the Installation
       disk to the EICON sub-directory on the file server. Use the COPY
       command as follows, substituting your drive letters as required:
           COPY A:\EICON\*.*  F:\EICON

       Files are: BIOS.ELM, BOPEC.ELM, BOPHSI.ELM, BOPI.ELM, BOPIBIOS.ELM,
                  DIAL.ELM, DIALBIOS.ELM,
                  OS_EC.ELM, OS_HSI.ELM,
                  RS_EC.ELM, RS_HSI.ELM,
                  VERIFCFG.ELM and
                  ECSDLC.MSG

    7. Copy the contents of the SYSTEM sub-directory on the Installation
       disk to the SYSTEM sub-directory on the file server. Use the COPY
       command as follows, substituting your drive letters as required:
           COPY A:\SYSTEM\*.*  F:\SYSTEM

       Files are: ECSDLCDR.LAN,
                  ECBIOS.NLM, ECCARD.NLM, ECLOAD.NLM, ECEXIT.NLM,
                  ECSDLC.NLM and ECSDLCX.NLM

ACTIVATING THE SDLC SUPPORT
===========================
Use NetWare's LOAD command to configure and start the SDLC support at both 
the PC and EiconCard level.

The LOAD command is used as follows (default values are shown):

LOAD ECSDLC  NAME=<see "NAME" below> [TYPE=HSI] [PHY=V.24] [PORT=380]
             [MEM=D000] [INT=3] [SLOT=1]

A parameter may be omitted when its default value is acceptable. Each 
parameter is described below.


NAME
----
NAME specifies the logical adapter name. There is no default value for 
NAME. You must enter this name in the "Logical Adapter Name:" field of the 
"SNA SDLC Configuration" screen displayed by CSCON, a NetWare for SAA V1.3
and later version command. Please consult the Novell documentation for
details.

NOTE: In NetWare for SAA V1.2, the bindery process relies on the
      "SDLC Adapter Type" value from the "SNA SDLC Configuration" screen
      displayed by CSCON.  The NAME= parameter is not used.
      The CSCON utility allows two IO port addresses: PRIMARY (380) and
      ALTERNATE (3A0).  The EiconCard supports IO port address 380,
      so you must select PRIMARY as the "SDLC Adapter Type".

TYPE
----
TYPE selects the type of EiconCard. The default value is "HSI".
Permitted values are:
    HSI
    EC

The bus-type (ISA/EISA or MCA) is automatically detected by the software.


PHY
---
PHY selects the physical interface. This is only required for HSI 
EiconCards. The default value is "V.24". Permitted values are:
    V.24
    V.35
    X.21


PORT
----
(ISA-bus and EISA-bus EiconCards only)
PORT must be set to the IO address that was selected for the EiconCard when 
it was installed. EiconCards are shipped from Eicon Technology set to 380.  
Permitted values are:
    280 378 380 388 390 398
    680 778 780 788 790 798


MEM
---
(ISA-bus and EISA-bus EiconCards only)
MEM specifies the memory segment configured for the EiconCard. The default 
value is D000h. Permitted values are:

    HSI and EC:
    C000 C200 C400 C600 C800 CA00 CC00 CE00
    D000 D200 D400 D600 D800 DA00 DC00 DE00

    HSI only:
    FC000 FC200 FC400 FC600 FC800 FCA00 FCC00 FCE00
    FD000 FD200 FD400 FD600 FD800 FDA00 FDC00 FDE00


INT
---
(ISA-bus and EISA-bus EiconCards only)
INT specifies the Interrupt Request level configured for the EiconCard. The 
default value is 3. The range of values depends on the selected EiconCard.
    HSI and EC: 2  3  4  5  6 7
    HSI only:  10 11 12 14 15


SLOT
----
(Micro Channel (MC) EiconCards only)
SLOT specifies the Slot number configured for the EiconCard in a Micro 
Channel PC. The default value is 1. Permitted values are: 
    1 2 3 4 5 6 7 8



DEACTIVATING THE SDLC SUPPORT
=============================
Use NetWare's UNLOAD command to halt and unload the SDLC support both at 
the PC and EiconCard level.

The UNLOAD command is used as follows:

UNLOAD ECSDLC



RELEASE NOTES
=============
The SDLC driver can handle one EiconCard at a time. Supported EiconCards 
are: EC/PC, EC HSI/PC, EC/MC, and EC HSI/MC. A DPNA EiconCard may be 
configured as an HSI EiconCard. In this configuration, only one of its 
ports may be used.

The EiconCard must be set to port 1.

External clocking is required.

Switched-line (dial-up) and leased-line operation is supported. When a 
switched line is used, the telephone number must first be programmed into 
the modem. With a switched line, the maximum amount of time the EiconCard 
dialer will wait for a connection is 45 seconds. The 45 seconds includes
dialing time, connection time, answer tones, and retrains that may occur
during modem connection.

NRZ and NRZI encoding are supported. Constant RTS (Point-to-Point) and 
Non-Constant RTS (Multi-Point) are also supported. These parameters are 
configured on the "SNA SDLC Configuration" screen displayed by CSCON, a 
NetWare for SAA command. Please consult the Novell documentation for details.

Release Notes for February 12/93
================================
* TYPE=HSI functions properly now.
* MEM=Fxxxx is handled properly now.
* The DTR signal returns to off after the timeout period (45 seconds)
  has expired during a connection establishment.
  
Release Notes for May 05/93
===========================
