I am currently having issues while trying to use ADTPro to connect to my Apple IIc and was wondering whether anyone could help me. I am using this serial connection kit and trying to bootstrap from ADTPro, but no matter what I seem to try it always ends up sending garbled text to the Apple IIc. I've tried it with my Mac and my Windows PCs and both produce the same result. For what it's worth, "PRINT PEEK(64447)" returns 0 so it seems that my Apple IIc shouldn't have the chip with the timing issue, but I can't quite put my finger on what is going wrong and I haven't found anyone else with the same issue. Here is a picture of what the garbled text looks like:

Update: Further testing with the baud rate set to 300 (on both PC and Apple IIc) and using Tera Term shows the following interactions with input from Tera Term:

  • @ types successfully
    • 01000000
  • A sometimes becomes P
    • 01000001 vs 01010000
  • a sometimes becomes X
    • 01100001 vs 01011000
  • B sometimes becomes h
    • 01000010 vs 01101000
  • C also sometimes becomes h
    • 01000011 vs 01101000
  • D sometimes becomes t
    • 01000100 vs 01110100

Perhaps there is a pattern there.

Getting garbled text when using ADTPro with Apple IIc and serial connection
