Programs that use ioctl(2) or curses(3x)
do not run in the User Program I/O Area as they would in a terminal
window. The User Program I/O Area is not designed as a fully functional
terminal emulator. However, you can still debug these types of programs
with HP/DDE.
One method is to run the program in a terminal window and
then attach the debugger to the process. See “Attaching the Debugger to
a Running Process ” for more information.
Another method is to use I/O redirection, as follows:
Start an hpterm
or xterm terminal
window with a running shell.
Run the tty
command in the terminal window to get its device name (for example,
/dev/pty/ttyp5).
Run the sleep
command in the terminal window to keep the shell from intercepting
any input (for example, sleep 100000).
Load the target program, but redirect standard I/O
to the terminal window, using the device name obtained in Step 2.
If you use the Load/Rerun dialog box, enter the device name
(which is /dev/pty/ttyp5
in this example) in the stdin,
stdout, and stderr
redirection input boxes.
When the target program starts, the User Program I/O area
disappears since all I/O has been redirected.
