Latest changes:
- serial port connects and disconnects are reported in the CLI
- PILBox connect status changes are reported in the CLI
- TRANSMIT ERR still occurs when there is a serial connection but no virtual IL device (PILBOX status is TDIS). This is intentional
- The HP-IL scope now shows the tracer sample counter for better correlation. There may be some jitter

About the trace counter: this is generated in real time for each HP41 T0-T0 cycle, even when the tracer is not connected, disabled or when samples are filtered. The shown trace samples lag behind the calculator activity.

Have fun and let me know your feedback.

"VERSION 00.01.05 BETA - build time: 2024/10/26_15:02:06" Updated on my development board today. All items noted in your post checked out. When connecting pyILPER the following are reported in the CLI:

Code:


  CDC Port 3 [HPIL] connected                                                   
  WARNING: No virtual HP-IL device connected, HP-IL loop may be open          
  PILBox mode changed to COFF / Controller OFF                                  
  PILBox mode changed to COFI / Controller OFF with IDY

The warning line seems out of place, given that pyILPER was just connected.

Cheers,
Craig (having fun!)
