You can also sign on with  term type 18 (HELLO username.acctname; TERM=18).
As for side effects, I haven't  noticed any loss  of  data with any of HP's
newer terminals (I think because  they have a larger  internal  buffer).  I
have  successfully  run  VPLUS (formspec)  and  TDP's  full  screen editing
without   any  loss.  If the  HP3000 is  bogged  down and   you are sending
hundreds of lines of data you may get some truncated though so be careful.
