Apple Disk Transfer ProDOS (ADTPro) Changelog

What's new in Apple Disk Transfer ProDOS (ADTPro) 2.0.2

Nov 14, 2016
  • New functionality:
  • Support added for Uthernet II based on new integrated IP65 library from Oliver Schmidt (http://oliverschmidt.github.io/ip65/)
  • Integrated John Brooks' ProDOS 2.4.1 as base operating system for all ADTPro actions (Speediboot, text bootstrapping, base disks, etc.)
  • [VDrive] Uthernet II virtual Ethernet driver from Oliver Schmidt that occupies the same space as the Disk II driver
  • Bug fixes/changes:
  • [VDrive] Default slot changed from slot 2 to slot 1 for virtual Ethernet disk drivers
  • [Ethernet] Fixes from Oliver Schmidt in ADTPro's interaction with the IP65 library make for much more reliable transfers with all Ethernet cards
  • [Audio] Fix buffer overruns causing stalled audio transfers due to pathological RLE compression
  • [Server] Sort directory contents explicitly for our Raspberry Pi friends
  • Skip initial serial ping request from IIgs to avoid blank screen when no connection exists at first

New in Apple Disk Transfer ProDOS (ADTPro) 2.0.1 (Mar 23, 2015)

  • New functionality:
  • Audio - Client sends test stream of data for volume tuning on host side
  • Server - Text bootstrapping data is packed more densely for faster transfer
  • Bug fixes:
  • Server and client agree on more situations where a transfer should be aborted
  • Client - Don't hang on a GS on startup if a connection isn't pre- established
  • Server - Flush the serial send buffer occasionally for our native serial port friends

New in Apple Disk Transfer ProDOS (ADTPro) 2.0.0 (May 26, 2014)

  • New functionality:
  • New protocol (code-named "Wide") that makes transport more reliable and significantly faster with tunable payload lengths
  • [Client] Arrow-and-Return interface for choosing a file to receive
  • [Client] Arrow-and-Return interface for the main menu
  • [Client] Directory listing allows for wildcard filtering of files, paging forward and backward
  • [SOS Client] Slow driver-based screen I/O subsystem replaced with custom code, significantly speeding up display
  • Separated ProDOS and SOS boot disks for ADTPro client; VDRIVE boot disk remains common to both
  • Bug fixes:
  • When the server decides to abort, the new protocol will not react to the "spray of commands" when the client (re-)sends data that isn't supposed to be commands
  • [SOS Client] Keyboard interaction works correctly
  • [SOS Client, SOS VSDrive] Changing serial connected-ness to the Apple /// no longer causes fatal SOS $02 errors
  • [SOS Client] Bare-metal bootstrap more reliable with timeout logic borrowed from Speediboot and made prettier with a logo and better display management
  • [Client] Hitting the escape key on the configuration screen truly aborts changes; this prevents DHCP from requesting a new IP address, for example
  • [Build] Re-architected 'Ant' build system to be completely dependency-driven; allows complete granularity of build targets

New in Apple Disk Transfer ProDOS (ADTPro) 1.3.0 (Apr 7, 2014)

  • Bug fixes:
  • Re-enable 19200 baud rate for serial client (removed in 1.2.8) - the Mac LC/Apple IIe card requires this speed

New in Apple Disk Transfer ProDOS (ADTPro) 1.2.9 (Dec 27, 2013)

  • New functionality:
  • [Client] Disk II drives turn on a little early to reduce spin-up delay
  • Bug fixes:
  • Nibble sends work correctly in batch mode
  • [Client] Nibble sends retry (more) correctly
  • [VDrive] Virtual disks are loaded once at initialization time, making it much faster for huge drives (but much less dynamic)
  • [VDrive] Serial driver installer quits to where it came from, allowing an invocation from the launcher to return there, this time with the driver in place

New in Apple Disk Transfer ProDOS (ADTPro) 1.2.8 (Jul 10, 2013)

  • [Server] Un-sign Apple's binary Java launcher so it doesn't confuse Mountain Lion [Client] Apple /// tries harder to consume buffered keystrokes before doing line-oriented input
  • [Client] Serial library is now non-blocking; allows for timeouts in times of failure; fixes speediboot pauses
  • [Server] If a 140k disk image isn't of a known format, take the filename extension into account before looking too much deeper
  • [Server] Serial over IP can specify both port and host, not just port

  • [VDrive] Aborts via escape key are more reliable, Ethernet now recovers correctly
  • [VDrive] Device driver installer filetypes changed to SYS

  • New functionality:
  • [Server] ShrinkIt "SDK" disk images are recognized and dealt with as any other disk image

  • [Client] Comms devices weren't being detected in the last slot (one of those off-by-one counting problems)
  • [Client] Apple /// Grub bootstrapper was using an uninitialized register in an alarming, but seemingly predictable, manner; initialize it for safety
  • [Client] Simplified UDP timeout processing after consultation with MagerValp

New in Apple Disk Transfer ProDOS (ADTPro) 1.1.0 (Sep 1, 2008)

  • Ported to run natively on the Apple /// under SOS
  • Added ProFile support
  • Plus bug fixes

  • [Client] Formatting was unreliable for 3.5" media due to unfortunate re-use of zero-page variable space

New in Apple Disk Transfer ProDOS (ADTPro) 1.0.5 (Feb 4, 2008)

  • [Server] Hosts with zero audio mixers (a Java thing) were crashing with java.lang.ArrayIndexOutOfBoundsException in AudioConfig.java.
  • [Client] IIgs serial port initialization was not working for speeds below 115.2kbps as a result of the 300 baud integration in v1.0.3.

New in Apple Disk Transfer ProDOS (ADTPro) 1.0.4 (Jan 31, 2008)

  • New: Support for 300 baud operation to help non-upgraded ROM 255 Apple IIc computers with the serial timing problem
