SIGINFO - not available (CrUn110)
The SIGINFO signal exists on Tru64 UNIX, but not on HP-UX.
SIGINFO is a BSD signal that the Tru64 UNIX terminal driver sends to the foreground process group whenever the user types the status character. That character can be set with the stty command and is usually set to Control/T. Some terminal-based applications that run for long periods of time use this feature to show their current status to the user. For example, a backup application might use a signal handler for SIGINFO to print the number of files backed up so far. Then, the user could check the status of the backup just by typing Control/T.
Review your code and applicable manpages to determine how to resolve this issue.
One possible resolution is to use the SIGUSR1 or SIGUSR2 signal instead of the SIGINFO signal, and have the user send it to the application with the kill command.
