Tek 4200 emulation on a 3130?

[HCART at VAX.OXFORD.AC.UK]

    Attached to our departmental ethernet we have, amongst other
machines, a few suns, some of which run uniras.  I would like
to use my 3130 to access a sun, emulating a tektronix 4200 series
terminal or similar.  Can it be done?  If so, how?
