This command loads into conventional memory the DNP variant that provides wide-area-network, asynchronous DECnet with NETBIOS support.
Guidelines
The DNNDCPPC command operates only in conventional memory. To operate asynchronous DNP from expanded memory, see the DNNDCPLD command.

DNNDCPPC
Sets the default flow control options for IOCB or NETBIOS interfaces, according to the following table:
Value NETBIOS Sockets
o
XONIXOFF XONIXOFF1 Segment Segment
Enables (Y) or disables (N) the INT 2A service. The default is Y.
Set to N if you use an alternate INT 2A interface.
Is the LANA number of the Ethernet adapter card that NETBIOS emulates. The value for n is either zero (0) or one (1). The default is zero. Set this value to 1 if you already have another NETBIOS emulator installed on LANA number O.
Is the number of local names in the volatile local adapter database. The value for n is from 2 to 64. The default is 16.
Specifies the number of node names in the DECnet node database, DECNODE.DAT. The range of values for n is 1 to 64. The default value is 12 or the number of MS-NET nodes defined in the DECnet node database, whichever is higher.
Adds (Y) or does not add (N) the local adapter names for the server and redirector to the volatile local adapter database. Y is the default.
Specifies the size in bytes of the largest message the session can support. The value for n is from 512 bytes to 65535 bytes (64 Kbytes). The default is 65535.
Sets the number of dynamic remote-adapter name entries that DNP reserves. The default is the number defined in the DECREM.DAT file.

DNNETH
uNNETH
Purpose
Loads the LAN variant of DNP with NETBIOS (DECnet, over Ethernet or Token Ring).
Guidelines
DOS loads DNNETH into conventional memory. To load and run DNP in expanded memory (EMS), load DNNETH.EXE into EMS with the EMSLOAD command.
Only one LAN version of DNP exists, and this version supports NETBIOS.

IADDR:address ICMD:n

IADDR:address Sets the client's node address. For IADDR to work, you must also supply the node name, using the !NAME qualifier. If you specify the node name and address, the system does not read DECPARM.DAT. Instead, DNP runs with default values.
/CMD:n Defines the maximum number of outstanding commands that can be added to the value computed by DNNETH. The value for n is from 0 to 256. The default depends on the number of DECnet links.

IFC:n Sets the default flow control options for IOCB or NETBIOS interfaces, according to the following table:
Value default method used by DNP to locate DECPARM.DAT.
112A:Y I N Enables (Y) or disables (N) the INT 2A service. The default is Y.
Set to N if you use an alternate INT 2A interface.
ILAN:n (Or ILANA:n) Is the LANA number of the Ethernet adapter card that NETBIOS emulates. The value for n is either zero (0) or one (1). The default is zero. Set this value to 1 if you already have another NETBIOS emulator installed on LANA number
o.
/MAX:n Configures the maximum number of DECnet links. The value for n is from 4 to 256. Each link requires approximately 212 bytes.
/MSN:n Specifies the number of node names in the DECnet node database, DECNODE.DAT. The value for n is 0 plus the number of names defined in DECNODE.DAT. Each node name requires 18 bytes.
!NAME:name Sets the client's node name. For !NAME to work, you must also supply the node address, using the IADDR qualifier.
IREM:n Sets the number of dynamic remote-adapter names that DNP reserves. The default is O. Each remote adapter requires about 170 bytes.
ISDB:n Sets the number of SDBs (small data blocks) that are allocated.
Example
SDBs store incoming and outgoing access control data and SELECT commands in progress. The value of n is from 5 to 32.
The default is 5. Each SDB requires 202 bytes.
You want to load your Ethernet DNP into conventional memory, with 2 remote adapter names, 30 commands, 4 DECnet links, and a path to the database for Ethernet LAN DNP with NETBIOS. Enter:
C: \> DNNETH lREM: 2 ICMD: 30 lMAX: 4 II: \DATADIR

DNPDCPPC
Purpose
This command loads the DNP variant that provides wide-area-network, asynchronous DEC net without NETBIOS support.
Guidelines
This variant can be operated only in conventional memory. To operate asynchronous DNP from expanded memory (EMS), do not use the use EMSLOAD command. Instead, use the DNNDCPLD command and specify the DNNDCPEM.EXE parameter.
Format
DNPDCPPC [drive: \ pathJ
Parameters
path Is the path to the databases (may include a drive letter).
Example
To load asynchronous DNP into conventional memory from a directory on the DOS path, enter:
C: \> DNPDCPPC
The screen displays:
DECnet DNP version V4.1
DECnet Node Name 'PLAYl' 9.380 DEC net Started
If DNPDCPPC has already been loaded, the screen displays:

EMSLOAD
Purpose
With this command, you can load individually the following network components into expanded memory (EMS): DNNETH, LAD, LANSESS, LAST, LAT, and RCV.
Guidelines
To use EMSLOAD, you must have expanded memory on your client.
For more information on loading network components into EMS, see Memory Solutions for Client Administrators.
Note ______________________ ___
Do not use EMSLOAD to operate asynchronous DNP from EMS. Instead, use the DNNDCPLD as described in this manual.
Format
EMSLOAD [drive: \ path \ component.exe] [/qualifiers/ .. .]
Parameters component
Qualifiers
/qualifiers
Is the network component you want to load into expanded memory: DNNETH, LAD, LANSESS, LAST, LAT, or RCV.
Are the qualifiers that define the way the component works.
Within limits, you can modify qualifiers at the command line. For valid settings, see the corresponding command for DNNETH, LAD, LANSESS, LAST, LAT, or RCVin this manual.

EMSLOAD
Exi:impie
You need to release some conventional memory for a large application by loading LAD into EMS. To do so, edit your STARTNET.BAT file as follows. The example assumes a path on drive C.
EMSLOAD c:\path\lad /r:4 /w:4 /a:d

LAD
LAD
Purpose
The LAD command starts the virtual disk client software, enabling you to use your virtual disk services.
Guidelines
To use the virtual disk client software, your client must be connected by a local area network (LAN) to a VMS system offering a disk service.
You can use this command to change the qualifier values even though LAD has already been loaded.
Before you run LAD:
• LAST should be running. Be sure that LAST precedes LAD in your STARTNET.BAT file.
• The device driver LADDRV.SYS must have been specified in your CONFIG.SYS file, as follows:
DEVICE = LADDRV.SYS /D:n
The value of n is the number of virtual disk drives to which you are connected. The range for n is 1 through 8. The default is 4.
