#I think this works:

Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:
#
#Another alternative is to send the ti string at startup time (and, I
#guess, the te string at exit time); that is how vi works in a cmdtool.
#The best reason to not do this is that this also disables scrolling
#which, as I understand it, is why anyone would use cmdtool in the
#first place.  Sending the ti string at startup time would do strange
#things on other systems too; in xterm it would use the alternate
#screen.
#
#The problem with cmdtool, in case that is less than obvious, is that
#almost none of the capabilities advertised in /etc/termcap are enabled
#while scrolling is enabled.  It has other problems too, like being
#part of an outdated proprietary windowing system, but there's probably
#no need to dwell on that.  In a sense, though, the sun-cmd termcap
#entry doesn't lie about the capabilities; I think the termcap man page
#does warn about some terminals having cursor motion capabilities only
#in the "ti/te window".
#
#A general solution to this problem would require a termcap capability
#which somehow tells which features are available outside of the ti/te
#window.  There is no such capability in termcap now, of course.
