There is a problem with the interaction between the Call protocol and 
TIOCSTI.  The problems occurs here with the 4.3BSD tahoe csh that
I have just put on the 310. The problem is that the input line generated by
TIOCSTI is not output to the terminal until the user types a character 
at the keyboard (or manually does a ^R). 

Repeat by:	First compile the bsd4.3 tahoe csh 
		There is a kernel bug in the handling of dup2 and dup.
		follow each occurrence of either of these in the file sh.misc.c
		with "(void) ioctl(k, FIONCLEX, (char *)0);"
		Run the shell and try the following:

		% set filec
		% ls /bin/d<CTRL D> 
		date	df	dis
		dd	diff	du
		% 

This behaviour also occurs on the /bin/csh that is supplied with Umax 2.2f. 
Does anyone know what the problem is and how to work around it.

Thanks,

Erick Delios
