Note that it does not work if a terminal window is open and connected to the ITF_HPIL (/dev/ttyACM2) serial port. In that case there is a "TRANSMIT ERR". On page 41 of the TULIP4041 documentation under "HP41 interface test" an instruction should be added to exit the ITF_HPIL terminal window if it is open at the beginning of this step. I'm wondering if this has contributed to the problem all along.

@rocket.scientist: I measured F1 on the module adapter with TULIP4041 disconnected and it is pulled up to V+ with the calculator on or off.

Thanks for that confirmation on FI. That was what I was hoping to hear. Let me investigate your ACM2 disclosure. I too wonder if that is my problem all along.

edit: I just checked my last log captures. HPIL port is closed. Drat!
