PMAC README (11/95)
-------------------

This README file contains information pertaining to the
installation, configuration, and operation of the Parallel
Port NDIS MAC Driver, PMAC.OS2, and its related files.


The PMAC package consists of:

  o PMAC.TXT   - This README file
  o PMAC.OS2   - The Parallel Port NDIS device driver
  o PMAC.MSG   - The message file for the driver
  o PMAC.EXE   - A utility that will connect/disconnect
                 the driver to/from the parallel port.


The PMAC driver is an NDIS (Network Device Interface
Specification) compliant device driver that enables the
Parallel port to emulate a NIC (Network Interface Card).

It will enable you to connect 2 PC's via the parallel port
to establish a point-to-point "network" using existing
protocol stacks.  The driver looks like an Ethernet
adapter to the protocol stack and uses a "LapLink" cable
for the connection.

To use this driver you will need 2 PC's with OS/2, a
"LapLink" parallel cable, and an NDIS compliant protocol
stack (e.g.  a pair of machines running:  OS/2 Peer, LAN
Server/Requester, LAN Requester in peer mode, TCP/IP,
etc.)


Installation/Configuration
--------------------------

The PMAC driver can be installed and configured using MPTS or
LAPS.  Simply install the driver as if it was a LAN Adapter.
Re-boot the 2 machines, connect them with the proper cable and
you are done.  If you plan on using other devices attached to
the LPT port (e.g. a printer) then you will need to add the
paramater /IRQ to the printer statement in the config.sys.  The
line should look like:

BASEDEV=PRINT01.SYS /IRQ
 or
BASEDEV=PRINT02.SYS /IRQ


Operation:
----------
Once the PC's are re-booted they are ready for networking.  If
you need to use the LPT port for any device other than the
PMAC, then you need to disconnect the PMAC from the LPT by
using the PMAC.EXE utility.

PMAC.EXE is a utility that will connect/disconnect the driver
to/from the LPT port.  To release the LPT port, change to the
IBMCOM directory and enter:  "PMAC -R" and the LPT port will be
released and usable by another device.  When you are ready to
reconnect the PMAC, enter:  "PMAC -C".
