I've seen the same thing on my vt420 with my IPX.  I haven't really
nailed it down yet, but I have suspected it has to do with serial
overruns.  My vt420 was in smooth scroll mode and I've turned it
off and haven't seen it again (although I haven't used it much
since I turned off smooth scroll).  I suspected an interaction
between the smooth scroll and maybe me not having modem control
lines right (got an IPX serial cable(sun) with a null modem to get
output on the vt420).

That help?
