I have seen this problem many times on many variants of OS including

	SUNOS 3.5
	SUNOS 4.0.3
	SVR3.2/i386 + Lachmann TCP

using both telnet and rlogin, using nn 6.3.10.  It has been around
for a long time (at least since nn 6.3.5) and the usual 
workaround is to hit ^L a few times until you see all the selections in 
the menu.  However the number of times it occurs is very low, maybe
once per nn session covering about 30 news groups.

Your followup seems to indicate that it is System-V termio specific,
but I beleive it isn't restricted to termio TCSETAF, as I've observed
it with BSD-environment compiled nn's too (SUNOS).
