A solution for developing XForms projects can bind an XForms template to a backend simulator, during a development or test stage of a software development. The XForms template can be developed by an interface designer, such as a business analyst. The XForms template can be conveyed to remotely located clients. Data instances associated with the XForms template can be received and routed to the backend simulator for processing. An integration code developer can later integrate the XForms templates to a backend server instead of to the backend simulator. Accordingly, the solution accelerates XForms based development projects by decoupling XForms interface development from XForms system integration development, which are typically handled by different people having different skill sets.

Using a backend simulator to test and develop xforms templates before linking the xforms templates to backend data processing systems

An information handling system includes a processor with one or more channels for communicating to peripheral devices controlled by peripheral device controllers, and one or more serial data links between the channels and the peripheral controllers. Data is transmitted over the serial data link between the channels and the controllers in a frame format, wherein each frame includes a number of eight-bit characters selected so that all standard parallel interface tag and data lines are transmitted in a single frame with a high degree of error immunity resulting from selection of idle characters and frame start characters having the mutual characteristic that single and double bit errors in the idle characters do not create an erroneous indication of a start character in the system.

Information handling system having serial channel to control unit link

Data is transferred between a channel and a control unit in interlocked mode or in data streaming mode over a conventional parallel bus and a serial link that permits the control unit and the channel to be located farther apart than the length of the parallel bus. The serial link carries frames for the rise of the data transfer tags but not their fall, and these tags on the parallel bus are dropped by two circuits that connect the serial link to the parallel bus. In data streaming mode, one data transfer tag is dropped when the next data transfer tag is received on the serial link. The circuit at the control unit end of the serial link detects a pause in the tags to begin an operation to drop the last data transfer tags and both circuits respond to other conditions to drop the last data transfer tags according to the protocol of the parallel bus.
