Table 8-1 “Intrinsics and Device Control” summarizes asynchronous device characteristics, settings and communication modes that may be affected programmatically through use of the intrinsics described in this chapter. It includes a brief explanation of how initial settings are determined. Unless stated otherwise, these settings remain in effect until the device is closed.
