INTRODUCTION This document describes the Digi Neo and ClassicBoard PCI Device Driver for Microsoft Windows NT 4.0. Refer to the following number when searching the Digi International Inc. Web site (www.digi.com) or the FTP site (ftp.digi.com) for the latest software package: 40002125_ 2. SUPPORTED OPERATING SYSTEMS Microsoft Windows NT 4.0 3. SUPPORTED PRODUCTS Model Number of Ports -------------------------------------- Digi Neo 2 Digi Neo 4 Digi Neo 8 ClassicBoard PCI 4 ClassicBoard EIA-422 PCI 4 ClassicBoard PCI 8 ClassicBoard EIA-422 PCI 8 4. KNOWN LIMITATIONS The driver supports ClassicBoard PCI adapters only. The ClassicBoard ISA adapter is not supported. AltPin and DTR/DSR flow control are not compatible. 5. ADDITIONAL NOTES Online help is available when you install the product. Installation documentation can be found at Digi's Web site, http://www.digi.com, or at Digi's FTP server, ftp://ftp.digi.com. AltPin ------ 10-pin RJ-45 plugs may be difficult to obtain in the retail market; therefore, the device driver software incorporates a feature called AltPin, which swaps the logical functions of DSR (Data Set Ready) with DCD (Data Carrier Detect). When the AltPin box is checked, DCD becomes available on pin 1 of an 8-pin RJ-45 connector (equivalent to pin 2 of a 10-pin connector). Force Baud Rate --------------- With the Force Baud Rate feature, the device driver software forces the baud rate of a COM port to a fixed value. This enables older serial communication applications to use baud rates above the applications configuration limit (e.g. 115200). If Force Baud Rate is enabled, the driver replaces the applications baud rate with the forced baud rate value. Drain UART Before Completing Write Requests ------------------------------------------- When enabled, the Drain UART feature forces the driver to wait for the UART to go idle before completing any outstanding write requests. The default behavior (disabled) emulates the behavior of the standard serial driver, which is to complete write requests as soon all the transmit data has been written to the FIFO (or transmit holding register, if FIFOs are disabled). 6. HISTORY Version 2.6.40.0 (Rev. G, June 08, 2005) ---------------------------------------- o Added support for Digi Neo 2 port rj45 adapter installation on Windows NT 4.0 o Added 9600 to the drop down list for configuring forced baud rate. o Improved processing of Read Interval timeouts Version 2.5.35.0 (Rev. F, June 09, 2003) ---------------------------------------- o Added workarounds for two Exar bugs when reading the TX and RX FIFO counters. o Added support for ClassicBoard EIA-422 PCI and Digi Neo 2 o Implemented feature, "Drain UART before completing write requests," to support application-level RTS toggle o Refitted driver to flush UART buffers when PurgeComm is called and device is flow controlled o Modified baud rate divisor calculation to better support non-standard baud rates Version 2.4.26.0 (Rev. E, August 08, 2002) ------------------------------------------ o Added support for MSCOMM32-based Visual Basic applications o Fixed port close so outstanding read requests are completed prior to closing the port o Fixed software flow control character echo failure o Augmented driver to accept arbitrary baud rates o Ports now appear in Print Properties dialog o Resolved COM port renumbering issue o Enabled force baud feature o Implemented on-board hardware flow control o Reinforced input buffer flow control processing o Remedied Isr / DpcForIsr race condition Version 2.0.3.7 (Rev. D, June 11, 2001) --------------------------------------- o Added AltPin support for alternative RJ-45 connectors o Added support for user definable baud rates o Added support to operate Digi Neo at 921600 bps. o Multiple adapters can now be installed without doing a re-boot o Set default COM port for installation to COM5 Version 2.02 (Rev. D1P, May 25, 2001) ------------------------------------- o Added support for Digi Neo adapters Version 2.01 (Rev. B, March, 1999) ---------------------------------- o Fixed RAS disconnect problem when multiple ports are active o Prevent use of COM names already claimed by other drivers o Cleaned up help file to remove old phone numbers Version 2.00 (Rev. A, September, 1998) -------------------------------------- o Added support for ClassicBoard PCI adapter o Fixed CITRIX systems failure caused if RTS/CTS handshaking is selected and the application never sets RTS signal, whereby the driver never raises the RTS signal o Added support for Rev. DC and later of the 16654 UART o Allow disabling of the UART's Transmit FIFO Version 1.02 (Rev. 1P, April, 1997) ----------------------------------- o Pilot release
