MS-DOS
Question:
I am running the IBM PC Lan Program for DOS, and the Microsoft DOS LAN
Manager. I also have a program that needs to use the DLC layer for the
MS-DOS machine in order to connect to a mainframe. I understand that
the current version of DOS LAN Manager (version 2.00b) does not expose
a DLC interface. How can I run DOS LAN Manager on top of IBM's NetBIOS
Stack?
Response:
It is true that DOS LAN Manager version 2.00 does not currently expose
the DLC interface, but it has been confirmed that DOS LAN Manager
version 2.00 will run on top of IBM's NetBIOS Stack.
The IBM PC Lan program will install the following in your CONFIG.SYS
file:
DEVICE=C:\PCLP\DXMA0MOD.SYS
DEVICE=C:\PCLP\DXMC1MOD.SYS
DEVICE=C:\PCLP\DXMT0MOD.SYS O=N ST=10 S=25 C=22 ES=2 EST=2
IFS=C:\PCLP13BS\REDIR.SYS
INSTALL=C:\PCLP13BS\IFSFUNC.EXE
The following steps can be used to get DOS LAN Manager version 2.00 to
use the DLC layer:
1. Install DOS LAN Manager as usual.
2. During the install process, select the protocol stack you want to
use.
3. After exiting DOS LAN Manager, remove any instances of device
drivers from CONFIG.SYS for DOS LAN Manager.
4. Remove both the "IFS=" line and the "INSTALL=" lines from your
CONFIG.SYS file. It is not necessary to load the IBM Lan Requester.
At this point, your CONFIG.SYS file should look like the following:
DEVICE=C:\PCLP\DXMA0MOD.SYS
DEVICE=C:\PCLP\DXMC1MOD.SYS
DEVICE=C:\PCLP\DXMT0MOD.SYS O=N ST=10 S=25 C=22 ES=2 EST=2
5. Remove NETBIND from your AUTOEXEC.BAT file since there is nothing
to bind now.
Since the Protocol Manager is not loaded, NETBIND is not needed and
the contents of PROTOCOL.INI are irrelevant.
Microsoft has confirmed that this configuration works correctly.
