Apple Disk Transfer ProDOS

Apple Disk Transfer ProDOS is a feature-rich communications platform for exchanging disks and disk images between the Apple II and Apple /// family computers and the modern world.

ADTPro has two main purposes in life:

• Transferring Apple disk images
• Bootstrapping Apple II computers when boot diskettes are long gone

ADTPro uses any of three communications mechanisms:

• Serial (RS-232, USB) hardware
• A2Retrosystems "Uthernet" LANceGS Ethernet card
• Audio/Cassette ports

Bootstrapping chores can occur with zero software at the Apple II end over serial and audio communications links.

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
