Set Keyboard Buffering (QWSSETWS) API

The Set Keyboard Buffering (QWSSETWS) API controls the type-ahead and attention key buffering functions for a display. With the QWSSETWS API, you can:

• Turn both functions off
• Turn both functions on
• Turn on the type-ahead function without buffering the Attention key
• Send the data stream to a specific device

Any changes to the keyboard buffering value made through this program take effect immediately.

The keyboard buffering data stream is supported by the ASCII Workstation Input/Output Processor, Twinaxial Workstation Input/Output Processor, 5394 Remote Control Unit, and 5494 Control Unit. Keyboard buffering for personal computer systems attached by IBM i Access or workstation emulation (WSE) is controlled through the emulation programs; these devices do not support the type-ahead data stream.
