FMP Programmer’s Guide
Each serial link on the FMP ICP can be configured as a receiver of one of several defined
market feeds. Each link operates independently of the other links on the same ICP and
can be configured with different communication options.
Data messages on the primary market feeds are broadcast using bisynchronous, asyn-
chronous, or isochronous frames. To receive the bisynchronous information, the Sim-
pact FMP product uses a variation of IBM’s 2780 or 3780 BSC protocol as described in
the document, General Information — Binary Synchronous Communications, IBM. To
receive the asynchronous and isochronous information, the Simpact FMP product uses
various settings of the FMP asynchronous communication capabilities. Refer to
Chapter 4 for more information about the FMP protocol options.
1.5.1 Software Description
Simpact’s FMP product includes the following major software components:
• A group of communications software downloadable images:
1. Freeway server or embedded ICP software
2. Real-time operating system (OS/Impact)
3. FMP communications software
• DLI library for linking with client applications
• A loopback test program (fmpalp.c) to check product installation (see
Appendix D)
• An interactive demonstration program (bscdemo) that allows a user to send indi-
vidual commands to the FMP software on Freeway. The
bscdemo program is
described in the BSCDEMO User’s Guide.
The Freeway User’s Guide or the user’s guide for your particular embedded ICP and
operating system (for example, the ICP2432 User’s Guide for Windows NT) describes
the software installation procedures. The DLI provides an interface by which data is
