Method Detail

getUdpServerCount

int getUdpServerCount()

Get the current count of configured UDP Servers without guessing

Returns:

int iNumber of UdpServers configured

createUdpServer

int createUdpServer(java.lang.String sPeerAddress,
                  int iPrimaryIpPort,
                  java.lang.String LocalIpAddress,
                  int iSecondaryIpPort,
                  java.lang.String sOperation,
                  int iDemarkationMsec,
                  int iBufferSize)
                    throws java.lang.Exception

Configure operating parameters for UDP Server minus the end device(s) parameters which use another method

Parameters:

sPeerAddress - In UDP_TO_SERIAL or UDP_SLAVE mode this parameter is used to bind() to the listen socket. A value of 0.0.0.0 would listen for any clients UDP packets. A value of 192.168.1.5 would only listen for packets from 192.168.1.5. In SERIAL_TO_UDP or UDP_MASTER mode this parameter is use to create the sendto() socket.

iPrimaryIpPort - In UDP_TO_SERIAL or UDP_SLAVE mode this parameter is used to bind() to the listen socket. In SERIAL_TO_UDP or UDP_MASTER mode this parameter is used to create sendto() socket.

LocalIpAddress - If Secondary port is not zero this this is the IP address used as the Source address of the outbound UDP packet

iSecondaryIpPort - In UDP_TO_SERIAL mode this parameter is not used. In UDP_SLAVE mode if this parameter is not zero then it is used as the port to forwarded serial packets at the last Clients IP Address. If set to zero then the packets are returned to the same IP Port that the client used in its source port of the UDP packet. In SERIAL_TO_UDP or UDP_MASTER mode if this value is not zero then the UDP packets source port is overridden to iSecondaryIpPort. If this value is zero then the source port will be set to 12345 + iUdpServerId.

sOperation - Use the service.UDP_TO_SERIAL to send packets from the network port to the serial port(s). Use the service.SERIAL_TO_UDP to send packets from the serial port(s) to the network port. Use the service.UDP_MASTER when the ESF system is a UDP Master so packets are originated on the serial port and the ESF system waits on UDP Packets as replies. Use the service.UDP_SLAVE when the ESF system is a UDP Slave so packets are originated on the network port and the ESF wait on serial packets as replies to go back to the network master.

iDemarkationMsec - This is used to determine when to stop building a payload of end device bytes and forward any previously received bytes to the TCP client in milliseconds.

iBufferSize - This is the maximum number of bytes that are to received from either the Client or the end device. If the buffer gets full then it is immediately returned to the other side of the UdpServer.

Returns:

int iUdpServerId This is the index to reference the object created by this configuration.

Throws:

java.lang.Exception

This method returns the Device driver used in a previously created UdpServer.

Parameters:

UdpServerId - This should be one of the Id's that is returned by the createUdpServer() method. This value ranges from 0 to 'last UdpServer Id'

ParallPortId - This should be one of the ParallelPortIds returned by createUdpServerParallelPort()

Returns:

DeviceDriver This is the device driver used for the end device. "PARALLEL_LP_DRIVER" is uses the native Linux parallel "PARALLEL_USB_LP_DRIVER" uses the native Linux usb parallel port driver (e.g. /dev/usb/lp[0-3]).

Throws:

java.lang.Exception

getUdpServerParallelPortEndDeviceIndex

This method returns the EndDeviceIndex of parallel port for a previously created UdpServer.

Parameters:

UdpServerId - This should be one of the Id's that is returned by the createUdpServer() method. This value ranges from 0 to 'last UdpServer Id'

ParallPortId - This should be one of the ParallelPortIds returned by createUdpServerParallelPort()

Returns:

EndDeviceIndex This is the index that is appended to the root device name such as.. /dev/lp? /dev/usb/lp? ...

Throws:

java.lang.Exception
