Liu Gao-song · Computer Technology and Development · 2006
Usually,the communication type between server and serial-equipment is point-to-point.But the communication between client and server is multi-thread parallel running.So it arises contradictions when multi-clients want to use one serialequipment on the server at the same time.Discusses the possibility of using program to control the client's requests and corresponding the resource distribution and data transfer between one client and another from the software side.And brings forward four solutions: locking for the serial operating function,set queue on the server,the second developing to the handshake protocol and quickly response.And then analyses the advantages and disadvantages of each other in practical situation.
