  • Page 115: Host Application Program

    While the 6950 EGS provides two way message services for the wireless network, it does not generate the messages. These come from a host program running independently of the 6950 EGS. In fact, the host application runs on a separate physical host. This section has some general information for communicating to the wireless stations and specific directions for using internet sockets.

  • Page 116: Native Sockets Overview

    Native Sockets let a host computer running a Native application communicate to Native wireless stations through the 6950 EGS via a TCP/IP socket connection. Native Sockets support is included in the 6950 EGS version 6.04 and greater. The remainder of this section explains Native Sockets programming.

  • Page 117: Host Programming

    As each wireless station powers on, the host application opens a unique socket between the 6950 EGS and the host for the wireless station. The 6950 EGS keeps an internal table mapping wireless stations to socket numbers.

  • Page 118: Coding The Application

    INTERMEC controllers that supported serial host communications. Addition of the sockets communication capabilities to the 6950 EGS required use of a modified Native Syntax. A cross reference is provided in the table that follows. Letter conventions are excerpted from the programmer's guide.

  • Page 119: Response Formats

    Error Messages The Native command syntax is processed partly by the 6950 EGS and partly by the wireless station. For example the Write Display command has an options list o" and message content x" in the form Do/x"<cr>. The 6950 EGS processes content preceding the forward slash while the wireless station processes content following the slash.

  • Page 120: Normal Communication

    Syntax checking is not done on messages transmitted through the 6950 EGS to the wireless station. Check the response to an asynchronous command for error notifications from the controller.

  • Page 121: Other Commands And Responses

    SECTION 10 Host Application Program For Write Display commands, the communication driver in the 6950 EGS adds the W." If the W" is included here, the message is rejected. The 6950 EGS allows three additional abbreviated Native commands for: StD", DtV", and Gt".

    SECTION 10 Host Application Program Program interfaces return the wireless station number and the controller or wireless station response. If one of these codes is not set, the field contains the number of the wireless station.

  • Page 125 Commands to the wireless stations must be in appropriate syntax for their Native mode. A good source for these commands is the programmer's guide available from us. Contact your Intermec representative to order the guide. The instructions for the wireless stations are helpful, but the commands for the controllers and bases should be ignored.
