I am using ADTPro with an Apple 2e and connecting to a MacBook that is running Windows inside VirtualBox.
I am able to bootstrap just fine. Additionally, when I "Send" the RAM disk, it goes nice and fast and copies everything.
However, when I try to send a disk, it will periodically stop and show a bad block ("X") and then proceed very slowly. The bad block does not always appear in the same place on subsequent attempts.
I have tried the same procedure over audio cables (using the Mac OS version) and the very same disks copied without issue.
I would do over audio for all disks if it were not so slow. I am trying to use the serial connection to save time.
Does anybody have any similar experience with trying to send data using a serial cable? Is there a solution?
