DRIVER INSTALLATION NOTES FOR PCI ADAPTERS
------------------------------------------
After installing one of the above adapters and booting the
machine, Windows will automatically install an older
version of the device driver. This version of the driver is
included as part of Windows, and it can also be found on
the Windows CD.
The Update Driver functionality available via the Device
Manager is not supported, however. Instead, to upgrade the
existing device driver for any of the above adapters, please
follow these steps:
a. First, uninstall the previously installed device driver.
From the Device Manager, expand the catagory "Multi-port
serial adapters". Right-click on the Digi adapter(s) you
would like to uninstall from the system and select
"Uninstall".
Be sure to uninstall each adapter that needs to be
upgraded.
b. Run the program Dgclean.cmd to move the existing INF files
for the adapter. This ensures that the new driver files
will be installed instead of the old driver files.
Dgclean.cmd is part of the driver software package and can
be found in the same directory as the new driver files.
c. Tell Windows to scan for new hardware. From the Device
Manager, right click and select "Scan for hardware changes".
The "Found New Hardware Wizard" should appear.
Alternatively, one may reboot Windows to conjure the
"Found New Hardware Wizard".
d. Follow the instructions for the "Found New Hardware
Wizard". From the "Locate Driver Files" screen, be sure
to select "Specify a location" to point the wizard to the
location of the new driver files.
e. Windows will display a "Digital Signature Not Found"
message, explaining that the driver is not signed. Click
"Yes" to continue the installation. One may see several of
these warnings -- simply click "Yes" for each message to
proceed with installation.
f. Follow any other instructions to complete the installation.
g. The "Found New Hardware Wizard" may reappear a number of
times depending on the number and type of adapters you are
installing.
DRIVER INSTALLATION NOTES FOR ISA ADAPTERS
------------------------------------------
ISA adapters are installed using the "Add Hardware Wizard".

5. HISTORY
Version 4.1.38.0 (Rev. B, May 05, 2003)
---------------------------------------
o Added support for Microsoft Windows Server 2003
o The following adapters are no longer supported by this driver:
Digi AccelePort 4r 920 ISA
Digi AccelePort 8r 920 ISA
Digi AccelePort 4r EIA-232 ISA/PCI
Digi AccelePort 8r EIA-232 ISA/PCI
Digi AccelePort EPC/X ISA
Digi PC/4e ISA
Digi PC/8e ISA
Digi PC/16e ISA
Digi PC/8i ISA
Digi PC/16i ISA
o Fixed EV_RXFLAG handling when EV_ERR is also requested.
o Modified parity, framing, and break error detection such
that events are now reported before the client issues a
read request.
o Fixed intermittent problem with too many characters being
reported in the receive queue.
o Fixed two ring events being generated instead of just one.
o Fixed an inaccurate ring buffer head pointer value used to
copy received data from the adapter to the driver. This
gave the appearance that the data in the ring buffer had
wrapped around, giving us a unusually high received byte
count and bogus data.
o Fixed a race on multi processor systems: one CPU inaccurately
reported a count of characters in the receive buffer which
included characters that the other CPU was simultaneously
removing.
o Added RTS toggle support for Xem, Xr, and Xr 920 adapters.
o Fixed RTS toggle to not slew character after dropping signal.
o Improved compatibility with standard serial driver.
o Fixed initial port settings to default to 1200,7,e,1 for
proper Plug & Play modem detection.
o Changed "Complete writes when transmit complete" feature
to default to on.
o Modified port open and set baud rate procedures to prevent
race condition when multiple ports are opened simultaneously.

driver from Windows 2000 to Windows XP or Windows .NET.
