Sun to HP3000 connection

[Ssi]

 I'd like to connect my Sun 3/160 to our HP3000 system. When I
try to run `block mode' applications from the Sun, the HP program
dies, something about terminal status. Character mode seems ok.
How can I emulate an HP 700/58 (I think) terminal on
the Sun???
                Thanks,
