// This Communications Component is implemented using separate Read and Write // threads. Messages from the threads are posted to the Comm control which is // an invisible window. To handle data from the comm port, simply // attach a handler to OnReceiveData . There is no need to free the memory // buffer passed to this handler. If TAPI is used to open the comm port, some // changes to this component are needed ( StartComm currently opens the comm // port). The OnRequestHangup event is included to assist this. // // David Wann // Stamina Software // 28/02/96 // davidwann@hunterlink.net.au

The files in this directory comprise ANSI-C language reference implementations of the CCITT (International Telegraph and Telephone Consultative Committee) G.711, G.721 and G.723 voice compressions. They have been tested on Sun SPARCstations and passed 82 out of 84 test vectors published by CCITT (Dec. 20, 1988) for G.721 and G.723. [The two remaining test vectors, which the G.721 decoder implementation for u-law samples did not pass, may be in error because they are identical to two other vectors for G.723_40.]

This taglib contains tags used to create struts input forms, as well as other tags generally useful in the creation of HTML-based user interfaces. Many of the tags in this tag library will throw a JspException at runtime when they are utilized incorrectly (such as when you specify an invalid combination of tag attributes). JSP allows you to declare an "error page" in the <%@ page %> directive. If you wish to process the actual exception that caused the problem, it is passed to the error page as a request attribute under key org.apache.struts.action.EXCEPTION.

The JavaServer Pages (JSP) Expression Language (EL) is a simple non-procedural scripting language that can be used to evaluate dynamic expressions within a JSP page. Each EL expression evaluates to a single value that is then expressed as text in the output of the JSP (when used in template text), or passed as a value to a JSP action. As such, it is ideal for adding dynamic elements to the HTML page (or other text output) generated by the execution of a JSP.

Mobile multimedia communication is increasingly in demand because of the basic need to communi- cate at any time, anywhere, using any technology. In addition, to voice communication, people have a desire to access a range of other services that comprise multimedia elements—text, image, animation, high fidelity audio and video using mobile communication networks. To meet these demands, mobile communication technologies has evolved from analog to digital, and the networks have passed through a number of generations from first generation (1G) to fourth generation (4G).

Electrostatic discharge (ESD) phenomena have been known to mankind since Thales of Miletus in approximately 600 B.C.E. noticed the attraction of strands of hay to amber. Two thousand six hundred years have passed and the quest to obtain a better under- standing of electrostatics and ESD phenomenon continues. Today, the manufacturing of microelectronics has continued the interest in the field of electrostatic phenomenon spanning factory issues, tooling, materials, and the microelectronic industry

If register should be written or read.This value is passed to the calback functions which support either reading or writing register values. Writing means that the application registers should be updated and reading means that the modbus protocol stack needs to know the current register values.See also: eMBRegHoldingCB(), eMBRegCoilsCB(), eMBRegDiscreteCB() and eMBReglnputCB().Enumeration values: MB_REG_READ Read register values and pass to protocol stack.MB_REG_WRITE Update register values.Note: Note all ports implement this function.A port which wants to get an callback must define the macro MB_PORT_HAS_CLOSE to 1.Returns: If the resources where released it return eMBErrorCode:: MB_ENOERR. If the protocol stack is not in the disabled state it returns eMBErrorCode:: MB_EILLSTATE.Examples: LINUX/demo.c, MCF5235TCP/demo.c, STR71XTCP/demo.c, WIN32/demo. cpp, and WIN32TCP/demo. cpp.his function disables processing of Modbus frames.Returns: If the protocol stack has been disabled
