Could it be that the computer is too fast for the EII ? try slowing the script down, sending smaller blocks at 'x' seconds interval. maybe 5 bytes at the time? >But when I the command >sring or the databytes in one move, the EII starts complaining. >Strange.

Could be major with upgrade packs of the emu stuff.
