Method Detail

configure

public void configure(PortConfig config)
               throws java.io.IOException,
                      java.lang.IllegalArgumentException

Update the configuration of the connector to match the updated setup.

Specified by:

configure in class PortConnector

Parameters:

config - PortConfig defining new port settings

Throws:

java.io.IOException - if interface changes could not be applied

java.lang.IllegalArgumentException - if type information is invalid for changing the settings of this PortConnector

close

public void close()

Shut down this PortConnector.

Overrides:

close in class Connector

hasLocalKissOverTcp

public static boolean hasLocalKissOverTcp(int portNum)

Test if the host computer is potentially running a Kiss-over-TCP server.

Parameters:

portNum - int TCP port number to test for a listening socket

Returns:

boolean true if the KISS-over-TCP service appears to be running

toString

public java.lang.String toString()

Produce a String describing this Connector.

Overrides:

toString in class java.lang.Object

Returns:

descriptive String

getCapabilities

public int getCapabilities()

Specify what capabilities a port of this type has. By default, returns a zero bitmask (not capable of anything). Expected to be overridden by subclasses.

Overrides:

getCapabilities in class Connector

Returns:

bitmask of capability flags

See Also:

Connector.CAP_RCV_PACKET_DATA, Connector.CAP_XMT_PACKET_DATA, Connector.CAP_FULL_DUPLEX, Connector.CAP_GPS_DATA, Connector.CAP_IGATE, Connector.CAP_OPENTRAC, Connector.CAP_RF, Connector.CAP_WAYPOINT_SENDER, Connector.CAP_WEATHER

isOpen

public boolean isOpen()

Reports whether this Connector has an open connection to its port.

Specified by:

isOpen in class Connector

Returns:

boolean true if Connector is open

sendFrame

public void sendFrame(AX25Frame frame)
               throws java.io.IOException

Transmit an AX.25 frame through this port. May fail silently if port is not configured for transmission (receive-only).

Specified by:

sendFrame in class TransmittingPortConnector

Parameters:

frame - AX25Frame object to transmit

Throws:

java.io.IOException - if transmit failed for any reason other than a receive-only port

failureGuiCreated

public void failureGuiCreated(PortFailureReporterIfc failureGui)

Specify the lazily-created failure reporting GUI object for the reported failure.

Specified by:

failureGuiCreated in interface PortFailureReportListener

Parameters:

failureGui - PortFailureReporterIfc object for the GUI

See Also:

GuiIfc.showIOFailureDialog(org.ka2ddo.yaac.io.PortConfig, String, org.ka2ddo.yaac.io.PortFailureReportListener)

failureGuiDismissed

public void failureGuiDismissed()

The GUI object has been dismissed by the user and should not be used any more by the requesting I/O code.

Specified by:

failureGuiDismissed in interface PortFailureReportListener

run

public void run()

Do not call. Reserved internal method for KissOverTcpConnector.

Specified by:

run in interface java.lang.Runnable

uncaughtException

public final void uncaughtException(java.lang.Thread t,
                                    java.lang.Throwable e)

Method invoked when the given thread terminates due to the given uncaught exception.

Any exception thrown by this method will be ignored by the Java Virtual Machine.

Specified by:

uncaughtException in interface java.lang.Thread.UncaughtExceptionHandler

Parameters:

t - the thread

e - the exception

getBitRate

public int getBitRate()

Get the bit transmission rate on this port.

Overrides:

getBitRate in class TNCConnector

Returns:

bit rate in bits per second (baud)

getFldigiVersion

public java.lang.String getFldigiVersion()

Get the version of Fldigi on the other end of the link. If the remote TNC is not an instance of Fldigi, this will return null.

Returns:

Fldigi version String, or null if not Fldigi

getModem

public java.lang.String getModem()

Get the last reported selected Fldigi modem from the remote TNC. If the remote TNC is not an instance of Fldigi, this will return null.

Returns:

current modem name, or null if unspecified/unknown

getModemList

public java.lang.String[] getModemList()

Get the list of Fldigi modems capable of supporting AX.25 packet frames. If the remote TNC is not an instance of Fldigi, this will return null.

Returns:

array of String modem names, or null if the remote TNC is not Fldigi

setModem

public void setModem(java.lang.String modem)

Send a modem changing command to the remote TNC (assumed to be an instance of Fldigi).

Parameters:

modem - name of modem (as reported by getModemList()) to use
