Berkeley Job Control on Hewlett-Packard

[Jerome Freedman]

	I am currently involved in a project requiring the management of two or
more processes using the same terminal, but under control of a server. I believe
that job control is required, but my initial attempts at implementing the 
project have met with (dismal) failure. This is most discouraging, especially
in the light of successful attempts using the same implementation on two other
manufacturer's UNIX machines.

	Specifically, I wish to use the following system calls:

		ioctl(0, TIOCSPGRP, &pid)
		kill(pid, SIGSTOP);
		kill(pid, SIGCONT);

Any ideas on why these calls seem to behave differently on the HP than on other
systems?
