public class EtherLiteDriver

extends PortDriver

implements Runnable

Version:

$Revision: 2.1 $ ($Date: 1997/02/19 18:00:00 $)

EtherLiteDriver(String)

This creates a new instance of a port driver with default options (no messages).

EtherLiteDriver(String, int)

This creates a new instance of a PortDriver with specified options.

run()

The receive thread; manages all response processing from the EtherLite device.

  public EtherLiteDriver(String hostName,
                         int options) throws PortIOException

This creates a new instance of a PortDriver with specified options. Any given copy of Java(TM) should have only one instance of a port driver per physical EtherLite device, so this class refuses to instantiate duplicate copies for a given device. Also, since EtherLite devices are not generally designed to be talked to by a large number of entities (typically just one or two hosts), multiple copies of Java running multiple copies of the EtherLiteDriver talking to a particular EtherLite device may run into a limitation at that device as to how many sockets it can have open. Currently, there is a 6 socket/device limit for most devices. Thus, if you want to talk to larger numbers of ports, it would be a good idea to do so from a common Java process if possible.

Parameters:

hostName - host name for device

options - lowest three bits set messageLevel defined in PortDriver

Throws: PortIOException

if communication with device not possible

  public EtherLiteDriver(String hostName) throws PortIOException

This creates a new instance of a port driver with default options (no messages).

Parameters:

hostName - host name for device

Throws: PortIOException

if communication with device not possible

  public void run()

The receive thread; manages all response processing from the EtherLite device.
