Software Description
The SunHSI/S 3.0 software package includes a network device driver and several
utilities to diagnose the functionality of the SunHSI/S device driver. Appendix E
contains a functional description of the SunHSI/S software.
Network Device Driver
The SunHSI/S 3.0 driver provides a streams-based interface to the Solaris operating
environment. The streams interface works with other products such as SNA 3270,
SNA peer-to-peer, X.25, and PPP protocols.
Diagnostic Utilities
The SunHSI/S 3.0 software supports bundled Solaris synchronous interface
diagnostic utilities (syncstat, syncloop, and syncinit) and also supports an
enhanced set of synchronous utilities (hsi_stat, hsi_loop, and hsi_init). These
synchronous utilities are described in Chapter 4.
Diagnostics
The SunHSI/S adapter supports a loopback diagnostic command, hsi_loop, that is
executed as a Solaris command from the workstation where the adapter is installed.
Loopback testing allows testing of the path from the processor to the point of the
loopback. The point of the loopback can be at the ISCC chip, a loopback plug, or the
local/remote modem. See Chapter 4 for further information.
