[ale] tcsetpgrp()

[Chris Fowler]

I made this little cheezy program to act as init for me on a floppy.  It spawns the shell just find.


Problem is that everytime I enter a command on the CL, I get following error message:



tcsetpgrp: Inappropriate ioclt for device.


It seems that all through the shell code the tcsetpgrp is being placed on STDIN.  So, Im thinking that in my efforts to 

spawn a daemon, I might have forgot something simple.  


Thanks,
Chris
