Establishing a TCP/IP connection in a client/server configuration between an OpenAccess SDK Client and an OpenAccess SDK service consists of the following steps.
1. A low-level TCP/IP connection is made from an OpenAccess SDK Client to an OpenAccess SDK Server that is listening on the specified TCP/IP port. See the following section Establishing a TCP/IP Connection for more information.
2. When this low-level TCP/IP connection has been established, the OpenAccess SDK Client exchanges operational parameters, or a handshake, with the OpenAccess SDK service. See Connection Handshaking for more information.
This chapter describes situations that may cause TCP/IP connections between an OpenAccess SDK Client and an OpenAccess SDK service to fail.
