  Not working:

  OS/2 4, snapscan 1236s, emx (gcc 2.8.1)

  This code:

  static SANE_Status read_calibration_data (SnapScan_Scanner *pss, void
  *buf, u_char num_lines)
  {
  static const char *me = "read_calibration_data";
  SANE_Status status;
  size_t expected_read_bytes = num_lines *
  calibration_line_length(pss);
  size_t read_bytes;

  DBG (DL_CALL_TRACE, "%s\n", me);
  zero_buf (pss->cmd, MAX_SCSI_CMD_LEN);
  pss->cmd[0] = READ;
  pss->cmd[2] = READ_CALIBRATION;
  pss->cmd[5] = num_lines;
  u_int_to_u_char3p (expected_read_bytes, pss->cmd + 6);
  read_bytes = expected_read_bytes;

  status = snapscan_cmd (pss->pdev->bus, pss->fd, pss->cmd,
  READ_LEN, buf, &read_bytes);

  tries to call snapscan_cmd to obtain 244800 bytes, but the maximum that
  sanei_scsi_cmd2 (USE_OS2) will cope with is 32K. This either causes
  a sigsegv or an assertion error (depending on whether debug mode or
  not).

  Increasing the value of MAX_DATA causes the aspi driver to trap the OS.

  A bientot

      If more is better, are double standards better than single ones?
