User`s guide

The SLTA-10 Adapter software will be installed in the SLTA sub-directory of your
LONWORKS directory, with the exception of the DOS network driver LDVSLTA. SYS.
This file will be installed in the BIN sub-directory of your LONWORKS directory.
To
install the DOS network driver into your CONFIG. SYS file, follow the instructions in
Chapter 8.
The SLTA directory will contain the following files:
l Read-Me File. The README. TXT file includes a list of all the files on the
distribution disk, and also includes any updates to the documentation that
occurred since the SLTA-10 Adapter documentation was printed.
l DOS Network Driver Sources. The SLTA-10 Adapter DOS network driver
source code is contained in the LDVSLTA directory. These files can be used as the
basis for creating drivers for hosts other than PCs running DOS (see also the
UNIX network driver sources). See Chapter 8 for a description of the SLTA-10
Adapter DOS network driver and Chapter 9 for a description of how to write an
SLTA-10 Adapter network driver for other hosts.
See Chapter 4 of the
LONWORKS Host Application Programmer’s Guide for a description of the
services that must be supplied by a LONWORKS network driver.
The source files to build the DOS driver are:
LDVSLTA.CFG Configuration file for Borland C.
MAKEFILE
Make file script for Borland C.
MDV-T1ME.C
Code to manage the PC timer.
MDV-T1ME.H External interface definitions for the timer handler.
MSD-DEFS.H
Data structure and literal definitions.
MSDeD1FC.C DOS driver interface functions.
MSD-DRVR.H DOS driver interface and literal definitions.
MSD-EXEC.C Main open, close, read, and write processing.
MSD-FRST.C Module to be linked first in the network driver.
MSD-IRQC.ASM Serial I/O interrupt procedure.
MSD-LAST.C Module to be linked last in the network driver.
MSD-RAW.C Direct serial I/O (modem) processing.
MSD-SEGD.ASM Defines data segment register for driver.
MSD-SI0.C PC/AT UART interface processing.
MSD-TXRX.C
Single byte link layer processing.
MSD-UART.H Defines PC/AT UART registers.
l External Interface Files. External interface files included for use by network
management tools are contained in the SLTA directory. External interface files
are included for the transceivers available for the SLTA-10 Adapter. See Binding
to a Host Node in Chapter 3 of the LONWORKS Host Application Programmer’s
Guide for a description of how to use these files to bind to an SLTA-10 Adapter
node. Appendix B of the LONWORKS Host Application Programmer’s Guide
provides a detailed description of how to modify these files to incorporate network
variables and message tags. These interface files are provided in version 3
