[webmin-devel] pty_process_exec

I am trying to get this to work but I get a "-1" as my $rv when I run it. I 
am not sure what I am doing wrong.

	&foreign_require("proc", "proc-lib.pl");
	($fh, $pid) = &proc::pty_process_exec("$driver -UR $pdline $sys $tab");
	while(1) {
		$rv = &wait_for($fh, "Are you sure you want to continue (Yy)\?");
		print $rv;
		if ($rv == 0) {
			print "Saying Yes";
			sysprint($fh, "y\n");
			}
		else {
			last;
			}
		}
	close($fh);


And my prompt looks like this when I run the command from the terminal:

This option will also remove all of the data.
Are you sure you want to continue (Yy)?

I need to type in "y" here and hit enter here.

I have also tried maney other patterns in place of "Are you sure you want to 
continue (Yy)?"

I even tried just "\?" or "\\?" nothing seems to work.

Thanks for your help
