	Let me preface this posting by saying that I am completely green
as far as apollo goes much less the wonderful world of Aegis.  "Prove it,"
you say.  Ok....


	I have an Apollo 3550 which we are running in the BSD environment.
I am trying to use a vt100 window with tip as a terminal emulator to talk
to our Vax 11/785 through the serial port.  In order to accomplish this
task the port must be configured for 8 bits, no parity, and 1 stop bit.

	Prior to envoking tip I used the Aegis command tctl to check the
current port settings and I find that they are just how I would like them
to be.  After envoking tip, however, the parity has changed from none
to even.  I attempt to use a ~s command in tip to set parity=none to no
avail.  When I show all the tip settings using ~s they indicate that parity
is set to none.  Using tctl however shows that the parity is still even.
If, after starting tip, I use the Aegis command tctl -parity none all works
well.  Why is it that I am not able to change the port characteristics 
using tip????

	I should add that I am using /dev/sio0 for the tip device.  I tried 
/dev/tty01 as well with the same results.  Any help/advice that can be
offered will be *greatly* appreciated.

Much Thanks--
	--tim

PS:  Please don't flame me with RTFM as the machines were delivered *without*
     a manual set :-( :-(
