  Updated to build using objasm instead of aasm.
  Sources changed to be objasm-compatible.
Admin:
  Requires Library 0.71 or later.
  Requires BuildSys 3.06 or later.
  Requires Env 0.65 or later.

Version 0.57. Tagged as 'DeviceFS-0_57'

Detail:

  * Exports C header file required by SoftIR module.

Admin:

  * Built on RPC.  SoftIR module compiled using the newly exported header.

Version 0.56. Tagged as 'DeviceFS-0_56'

Detail:
  lr was being used as a temporary register to store the buffer handle in
whilst checking for ownership.  If DeviceFS didn't own the buffer the call
was being made on, it then used this value in a MOV pc, lr thus going who
knows where...

Admin:
  Checked and still works.  Appears to cure previous problem where issuing
Upcall 8 could cause a branch through zero error.

Version 0.55. Tagged as 'DeviceFS-0_55'

Version 0.54. Tagged as 'DeviceFS-0_54'

Version 0.53. Tagged as 'DeviceFS-0_53'

Bug fix: DeviceFS was inadvertently enabling interrupts when generating the Upcall to indicate that new data has arrived in an input buffer.

Detail:
  DeviceFS was using OS_UpCall to generate a UpCall_DeviceRxDataPresent
  upcall for for the wake up event (when data was inserted into a dormant
  receive buffer).

  However, OS_UpCall enables interrupts, contrary to the RISC OS 3 PRM.
  Since it happened within the hardware modem interrupt handler, this is
  quite dangerous and can lead to the modem interrupt handler being
  re-entered, thereby corrupting bytes or putting bytes into the buffer in
  the wrong order.

Admin:
  SCTransport v0.57 or later is needed if using this version of DeviceFS
  (since earlier versions relied on this incorrect behaviour in DeviceVS).

  Unfortunately, Pace fault 2098 still exists after making this change
  (Chip to Server transactions are very slow in Customer F 8 using a HW modem).

Version 0.52. Tagged as 'DeviceFS-0_52'

Detail:
  The UpCall handler was using MOVEQS pc, lr to pass on the vector in
    some cases.
  Fixed a non-internationalised build bug - missing condition in macro.
Admin:
  Built.

Version 0.51. Tagged as 'DeviceFS-0_51'

  Added stripdepnd to MkClean
Detail:
  Replaceed -throwback with ${THROWBACK} so that throwback isn't generated
  in ROM builds, but still works for local test builds.
Admin:
  Tested on Ursula build.

Version 0.50. Tagged as 'DeviceFS-0_50'

Version 0.49. Tagged as 'DeviceFS-0_49'

Some stray border flash debugging removed. FSEntry_Args code for extent was broken in the non-FastBufferMan case (not that this will ever have been used).

Version 0.48. Tagged as 'DeviceFS-0_48'

Detail:
  Also fixed faulty debug code which tried to report the escape state,
    but would have always failed to do.
Admin:
  Tested Phoebe and 32 machine builds.  Tested on Risc PC.

Version 0.47. Tagged as 'DeviceFS-0_47'

Version 0.46. Tagged as 'DeviceFS-0_46'

Added purging of output buffer if checkfileTXOK returns an error to get round the problems of paper out on lexmark printers.

Version 0.45. Tagged as 'DeviceFS-0_45'

German resources imported. Capitalisation of "IOCtl" fixed.

Version 0.44. Tagged as 'DeviceFS-0_44'

Changed to pass device driver stream handle to DeviceDriver_IOCtl, rather than the DeviceFS stream handle. WARNING! Anyone that was relying on the broken behaviour will have to change their code.

Version 0.43. Tagged as 'DeviceFS-0_43'

Version 0.42. Tagged as 'DeviceFS-0_42'

Changed to use srccommit.

Version 0.41. Tagged as 'DeviceFS-0_41'
