Interface ITermServService

public interface ITermServService

The ITermServService is used to give from one to eight network clients access to one or more serial ports or a single parallel printer port. If more than two or more client are simultaneously accessing a serial port then the TermServ should be in half duplex so that resource protection can be used on the serial port.

                   int iMaxAcceptedSockets,
                   java.lang.String sOperation,
                   boolean fPrintServer,
                   java.lang.String OpenModbusMode,
                   int iDemarkationMsec,

                   throws java.lang.Exception

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

Parameters:

iListeningPort - TCP/IP Port that TermServ will listen on. OpenModbus uses port 512. User ports > 1024. This is also used as a unique key so if you access this method with same port then same object will get reused.

iMaxAcceptedSockets - Number of active Terminal Servers allowed on the same TCP port from 1 to 8. If set to 1 then the port will be pre-emptive.

sOperation - Use the service.FULL_DUPLEX for normal Terminal server operation. This mode should only be used in pre-emptive mode. service.HALF_DUPLEX will allow multiple Clients to access the same end device(s) using resource protection. service.BROADCAST will send data to end device and will never receive anything from end device(s).

fPrintServer - If 'true' then attempt to guarantee that all bytes are sent to end device(s) even if pending bytes are in buffer and the socket closes.

OpenModbusMode - Use service.OPENMODBUS_TO_RTU for conversion from OpenModbus-TCP packet to RTU Modbus at the end device(s). Use service.OPENMODBUS_TO_ASCII for conversion from OpenModbus-TCP to ASCII Modbus at the end device(s). Otherwise use "" or service.NO_MODBUS

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.

iResponseTimeoutMsec - This configures the Terminal Server running in HALF_DUPLEX mode how long to wait for the first byte before releasing the end devices resource(s) upon receiving no data.

iIdleTimerSeconds - The Terminal Server will close the connection to the Client if no traffic is detecting after this period of seconds. Use a value of zero to instruct the Terminal Server to ignore any inactivity.

iDefragTimerMsec - This is used help the Terminal Server reconstruct any fragmented message from the Client so that it can be reassembled into a single packet before sending it to the end device(s).

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 Terminal Server.

sPassword - If this parameter is empty ("") then a password will not be required before the Terminal Server will allow access to the end device(s). The maximum string length is 16 characters. The client has 60 seconds to correctly enter the password.

Returns:

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