Using Simulated I/O
Simulated I/O is a feature of the emulator/analyzer interface that lets you use the
same keyboard and display that you use with the interface to provide input to
programs and display program output.
To use simulated I/O, your programs must communicate with the simulated I/O
control address and the buffer locations that follow it. (The Hewlett-Packard AxLS
compilers, if your program uses I/O, automatically link with environment
dependent routines that communicate with the simulated I/O control address and
buffer.)
Also, before simulated I/O can work, the emulator must be configured to enable
polling of the simulated I/O control address and to define the control address
location.
This section shows you how to:
•
Display the simulated I/O screen.
•
Use simulated I/O keyboard input.
Refer to the Simulated I/O User's Guide for complete details on how simulated I/O
works.
To display the simulated I/O screen
• Choose Display→Simulated IO.
Before you can display simulated I/O, polling for simulated I/O must be enabled in
the emulator configuration.
