***************************************************************************** ----------------------------------------------------------------------------- DEVICE DRIVERS INTERNATIONAL, LLC welcomes you! -> All DEVICE DRIVERS INTERNATIONAL products are meant to be SIMPLE and EASY. -> As such, there isn't a ton of documentation. You don't need it. -> We cannot provide FREE technical support for this driver. -> Please read the license agreement! Driver Name: RS485NT.SYS Operating System: Windows NT v4.0 Description: A generic RS485 driver that utilizes RTS to enable the RS485 multi-drop driver enable. ----------------------------------------------------------------------------- ***************************************************************************** The driver files: ----------------- RS485NT.SYS Windows NT Kernel-Mode driver RS485NT.REG Regsitry entry for the driver The source files: ----------------- Q_TEST.C Quick test of the driver (shows how to use it!) RS485NT.C Windows NT 4.0 RS485 driver source code RS485NT.H Device extension structure for source code COM8250.H Standard 8250 UART defines RS485IOC.H IOCTL codes (used in both Q_TEST and RS485NT) RS485NT.LNR Linker "Release" command file RS485NT.LND Linker "Debug" command file MAKEFILE NMAKE compatibile make file SETENV.BAT Sets the necessary PATHS for compiling README.TXT This file *NOTE* ------ For obvious reasons we cannot supply the Microsoft tools, libraries, or includes. You need to purchase an MSDN subscription! ----------------------------------------------------------------------------- ***************************************************************************** Loading the driver: 1) Un-zip the file RS485NT.ZIP in a new directory 2) Copy RS485NT.SYS to the SYSTEM32\DRIVERS directory under the Windows NT system directory. 3) Launch REGEDIT.EXE and Import the file RS485NT.REG 4) Adjust the registry entry for RS845NT, if a change is necessary. The driver defaults to the settings for COM2, 19200 baud 5) Re-boot the machine ----------------------------------------------------------------------------- ***************************************************************************** Building the driver: 1) Make sure SETENV.BAT is modified for your particular system 2) Type NMAKE ----------------------------------------------------------------------------- ***************************************************************************** Known problems: --------------- The Microsoft NT driver SERMOUSE.SYS has a BUG! If RS485NT is allocated with the same Comport I/O and IRQ as your mouse, then SERMOUSE.SYS will generate a page fault and halt Windows NT. -> IF YOUR MOUSE IS ON COM1, CONFIGURE RS485NT FOR COM2. -> IF YOUR MOUSE IS ON COM2, COMFIGURE RS485NT FOR COM1. The fix: -------- If SERMOUSE.SYS page faults, re-boot under another OS or use the Last Known Good settings, then delete the RS485NT.SYS file under the DRIVERS subdirectory. Use REGEDIT to change the I/O base and IRQ used by RS485NT.SYS Search for RS485NT and edit any of the registry keys there. Registry Entries: ----------------- Port Address = 2F8 (COM2) and 3F8 (COM1) IRQ Line = 3 (COM2) and 4 (COM1) Baud Rate = 19200 (4B00 HEX), 38400 (9600 HEX), 57600 (E100 HEX), 15200 (1C200 HEX) Buffer Size = Minimum 1024 (400 HEX) ----------------------------------------------------------------------------- ***************************************************************************** LICENSE AGREEMENT FOR DEVICE DRIVERS INTERNATIONAL SOFTWARE This legal agreement between you, the customer or end user, and DEVICE DRIVERS INTERNATIONAL gives you certain rights, benefits, and obligations.
