  That's part of the EPSON communication protocol: When the scanner
  sends STX as an acknowledge message then it has more data to
  transmit. A command that does not produce any scanner data is
  answered with ACK (set resolution will only send ACK to let
  the software know that it was able to set the resolution),
  get identity will send information about the scanner, so it
  will first send STX, which also means that the length of
  the data block is transmitted after the STX.

  0xf2 is something the scanner will never produce as return code,
  this again is an indication for SCSI problems (as I suggested
  before). Unfortunately I don't have access to any flavour of
  BSD so I can not test this myself. Is anybody on this list
  using an EPSON SCSI scanner with BSD?
