This document is available in an HTML version that is specialized for accessibility. You can navigate the HTML with an adaptive technology such as a screen reader, or view it with a screen enlarger.
EAServer 5.2 and the HTML documentation have been tested for compliance with U.S. government Section 508 Accessibility requirements. Documents that comply with Section 508 generally also meet non-U.S. accessibility guidelines, such as the World Wide Web Consortium (W3C) guidelines for Web sites.
The online help for this product is also provided in HTML, which you can navigate using a screen reader.
For information on using this product without a mouse, see “Keyboard navigation” in Chapter 2, “Sybase Central Overview,” of the EAServer System Administration Guide.
You might need to configure your accessibility tool
for optimal use. Some screen readers pronounce text based on its
case; for example, they pronounce ALL UPPERCASE TEXT as initials,
and MixedCase Text as words. You might find it helpful to configure
your tool to announce syntax conventions. Consult the documentation
for your tool.
For information about how Sybase supports accessibility, see Sybase Accessibility. The Sybase Accessibility site includes links to information on Section 508 and W3C standards.
Each Sybase installation that has purchased a support contract has one or more designated people who are authorized to contact Sybase Technical Support. If you cannot resolve a problem using the manuals or online help, please have the designated person contact Sybase Technical Support or the Sybase subsidiary in your area.
