I don't know how much setting Tty/Retained = "YES" will help, as we are still
running 2.2, but one change that does improve things greatly is to add AL and
DL (multiple add and delete line) capabilities to your termcap entry.  

Here is the termcap entry we use here at Columbia:

# --------------------------------

# S: Sun Workstations, Silicon Graphics Iris Workstations
#
SM|sun|Sun Microsystems Workstation console:\
	:li#34:co#80:cl=^L:cm=\E[%i%d;%dH:nd=\E[C:up=\E[A:\

	:rs=\E[1r:
S-|sun-nic|sune|Sun Microsystems Workstation console without insert character:\
	:ic@:IC@:im@:ei@:tc=sun:


I don't know for sure whether the 3.x releases support multiple insert/delete
line, but I would be surprised if they didn't.  Note that adding AL/DL
capabilities is preferable to removing al/dl (or adding hefty padding values to
them so they won't be used).  See the file gnu/dist/INSTALL for a longer
discussion of how to tune your termcap.
