Application Program Interface

As shown in Figure 3-4, application programs may interface with

Smart-Frame systems and systems using the HBC or RS-232 controller

directly via the Smart-Frame Protocol. Smart-Frame systems and

systems using the RS-232 controller are identical in terms of software.

Both communicate using the Smart-Frame Protocol via the RS-232

serial interface. Systems using the HBC communicate with the

application program using the Smart-Frame Protocol via the HBC I/O

registers. For more details about the I/O registers, see “HBC I/O

Registers” later in this chapter. The SBC cannot use the Smart-Frame

Protocol directly because the SBC has no processor on board. The

Smart-Frame Protocol is discussed in Chapter 4, “Smart-Frame

Protocol.”

As also shown in Figure 3-4, application programs may interface with

Smart-Frame systems and systems using the SBC, HBC, or RS-232

controller using the Smart-Frame Protocol via a Touch Application

Program Interface (TAPI) driver. This is the same Smart-Frame

Protocol used when interfacing directly to the touch system hardware.
