In a client-server mode, the PC running Linux can serve as the server while the control computer makes requests for change of instrument status as a client. If the receiver builder chooses a PC platform, Linux OS may be a better option because of the network setup and configuration tools and its superiority to NT in overall performance as a server. Advantages Less expensive. The PC option is only good if the receiver does not need any real-time control. Both Linux and NT are not true real-time OSs like VxWorks.
New software needs to be written to set up the communication links.
