    I am running an interactive program with stdin, stdout & stderr all
set to the slave side of a pty (so it thinks it's in a terminal.)  It
puts the terminal in raw mode.  I want to wait until
my slave program is waiting for an input character from the terminal.
I tried select() on the master but that didn't work.
I also tried resetting the process group of the terminal and waiting
for the SIGTTIN but this seems to stall the slave process permanently.
What do I do?  I am running under SunOS 4.0.
