Abstract: A method of transmitting data and command through an RS232 serial port incorporated with a user-end device and a server-end device connected through the RS232 serial port is disclosed and includes following steps: accumulating a value of a first counter of the user-end device and a value of a second counter of the server-end device whenever a data is transmitted from the server-end device to the user-end device; controlling the server-end device to stop transmitting the data and to wait when both of the two values reach a triggering threshold; controlling the user-end device to transmit a control command to the server-end device through the RS232 serial port while the server-end device is waiting; and, resetting the first and the second counter and controlling the server-end device to restore to transmit the data to the user-end device after a waiting time is elapsed.

Abstract: A method for editing continual vertical line of visual programming language includes following steps: entering an editing mode; selecting a source node as a current node from a serial-parallel graphic where the source node is an endpoint of one of a plurality of normal blocks in the graphic; calculating and displaying one or more candidate nodes around current node; connecting the current node to any one of the candidate nodes for converting the connected candidate node into a connected node; setting the connected node as the current node for continually calculating, displaying, connecting to one or more candidate nodes before exiting the editing mode; generating a continual vertical line according to the source node and the one or more connected nodes when exiting the editing mode; modifying the serial-parallel relationship among the plurality of normal blocks in the graphic and updating the graphic according to the continual vertical line.
