1.0 WHAT'S NEW IN RELEASE 3.40
This release corrects a minor typo in a dialog box.
Previous Versions:
Release 3.30
This release adds support for the Windows H/PC computers running
Windows CE Professional Edition (Jupiter). Additionally, the
Windows CE installer has been upgraded to utilize the Windows
CE Services 2.x Application Manager.
Release 3.20
This release fixes a known problem with Windows NT 4.0. Included is a
new Dual Serial Control Panel applet that will run under Windows 9x and
NT 4.0. This product requires third party Card & Socket Services in order to
function under Windows NT 4.0. Softex and Phoenix both make such a
product and both have been tested with the D-I/O.
You can purchase the Phoenix Card Executive for Windows NT 4.0 from
Socket by contacting our sales department at 510-744-2700, or fax
at (510) 744-2727. You can also e-mail Socket at info@socketcom.com
or visit our web site at http://www.socketcom.com.
The logging capability available in the previous driver has been removed
since it is no longer necessary.
Release 3.11
This release adds an enhanced Windows NT 4.0 driver, plus a logging
capability in the NT driver. The Control Panel applet has been updated
to allow turning on or off the event logging. In some cases, there has
been an unidentified problem with the dualio.sys correctly enabling the
card under Windows NT 4.0. If the problem exits, an error message will
appear in the Control Panel applet that says, "Cannot Detect Com Ports".
There is currently no workaround available for the problem.
Release 3.00
This release includes the addition of Windows CE drivers and DOS Direct
Enablers.
Release 2.01
This release corrected a problem where the Dual I/O could not be
configured by Windows NT 4.0 on some notebooks. The file DUALIO.SYS was
updated.
Release 2.00
This release included a driver for Windows NT 4.0, and fixed the
problem of using COM 5 on Windows 95. There was a new option in
the Control Panel applet which can indicate advanced configuration
information.
