Using the SPX protocol
Because SPX is a connection-based service,
it reliably delivers data and notifies the user
if any errors occur during data transmission.
Upon encountering a data transmission error,
SPX retries a certain number of times before
closing the connection and notifying the connection user.
SPX also notifies the user if a
disconnection indication is received from the
remote connection endpoint.
SPX functions in both synchronous and asynchronous modes. The application developer determines the mode.
Applications access SPX using TLI (the Transport Layer Interface). This chapter assumes that you are familiar with NetWare communication processes and TLI. For information on these topics, see:
