Data Transfer Function Overview

PC400 can transfer data between the host and workstation. The data transfer function can be invoked manually by clicking the Data Transfer icon. The Data Transfer application is automatically invoked from a 5250 session when you click Send File to Host from the Actions menu and Receive File from Host from the Actions menu. You can change this default to invoke normal file transfer functions; to do so, click Preferences → Transfer from the Edit menu, then click the Data Transfer radio button on the property page with the General tab.

Transferring data, described in this chapter, is quite different from transferring files, which is described in File Transfer for PC400. The main differences are listed in the following table.
