Asynchronous is a form of data transmission in which individual characters are sent one at a time, delineated by a start bit and a stop bit. Using the client-server model, the client is the requesting program or user and the server (host) is the program or user that handles these requests from the clients.
EC Gateway supports different types of asynchronous communications:
pfs/Async
Other, third-party asynchronous communication programs
The communication product, pfs/Async, supports asynchronous protocols and uses a modem and a dial-up telephone line. pfs/Async can be used in the host or the client mode. For both modes, you first define a communications channel as described in Chapter 1, “Accessing EC Gateway.”
