  1. ; future docs designed here:
  2. ; SAVEDEV <filename>,<startPage>,<startOffset>,<length>
  3. ;   Works only in real device emulation mode. See <link linkend="po_device">DEVICE</link>.
  4. ;
  5. ;   Like <link linkend="po_savebin">SAVEBIN</link>, saves the block of device RAM.
  6. ;
  7. ;   But it allows lengths over 64ki, and the offset value goes directly into device
  8. ;   virtual memory (where pages are allocated consecutively), ignoring current slot
  9. ;   "mapping". I.e. page=2,offset=0 will start saving data from page 2 at its beginning,
  10. ;   going through pages 3, 4, 5, ... until the requested length of data is saved.
  11. ;
  12. ;   The offset is not limited to page size, i.e. arguments page=1,offset=0x500 are equal
  13. ;   to arguments page=0,offset=0x4500 for ZXSPECTRUM128 device (has page size 0x4000).
