The Client Option supports concurrent use of multiple network drivers, providing additional flexibility and ease of installation for sites configured to run TCP/IP.

The network drivers can be invoked from the same Client Option and Server Option common code base. The appropriate network driver is loaded dynamically at the time the program executes.

You must use the SYGWDRIV macro to define the network drivers to be used with the Client Option and Server Option. For each operating environment, the default SYGWXCPH member provided contains the SYGWDRIV macro definitions for all of the supported network drivers pertinent to the technology. The person installing the Client Option should edit the appropriate IxHOST member to comment-out the drivers that your site does not intend to use.
