It looks like I summarized too soon. Even after modifying zsadtrlow
to 5, I had DTR not get raised this morning. I have included a
message from Tim Tessin ( who let me know those of us
with 4.1.1 will just have to wait.

My initial message:

His response:

This probably won't help. There is a bug in the SunOS kernel/getty having to do
with this problem. I have been fighting Sun on this for 3 months! It is
Bug ID1060689. It occurs on ALM-I, ALM-II, SPC/S, Sun3, Sun4 (all 4.1.1) and
I presume, ttya/b (zs). A beta patch is due sometime around the 19th and full
patch probably Sept 1 timeframe. Contact Sun support to get on the list for
information. I believe the problem is in "getty" and it is exacerbated by
CTS/RTS handshaking. Symptoms are CPU drops DTR and leaves it....
