Method Detail

getName

java.lang.String getName()

Returns:

the port name, typically an OS-dependent hardware label.

getPortType

int getPortType()

Returns:

the port type, PORT_SERIAL or PORT_PARALLEL.

getCurrentOwner

java.lang.String getCurrentOwner()

Returns:

the current owner of this port.

isCurrentlyOwned

boolean isCurrentlyOwned()

Returns:

true if this port is currently owned.

open

CommPortInterface open(java.lang.String appName,
                       int timeout)
                       throws PortInUseException

Parameters:

appName - the name of the application requesting the port

timeout - number of miliseconds to wait for the port to open

Returns:

communications port. If the port is in use by another application, it will be notified with a PORT_OWNERSHIP_REQUESTED event. If the current owner closes the port, then this method will succeed. Otherwise a PortInUseException will be thrown.

Throws:

PortInUseException

open

CommPortInterface open(java.io.FileDescriptor fd)
                       throws UnsupportedCommOperationException

Parameters:

fd - the file descriptor

Returns:

a port using a file descriptor.

Throws:

UnsupportedCommOperationException - if the platform does not support this functionality

addPortOwnershipListener

void addPortOwnershipListener(CommPortOwnershipListener listener)

Adds the specified listener to the list of ownership listeners for this port.

Parameters:

listener - the ownership listener to add

removePortOwnershipListener

void removePortOwnershipListener(CommPortOwnershipListener listener)

Removes the specified listener from the list of ownership listeners for this port.

Parameters:

listener - the ownership listener to remove
