Exchange programs from a "11C" calculator to a Windows or Android emulator is possible
with a single calculator model: the DM11L
and with the NutEm/PC emulator on Windows
and with the Touch RPN 11C emulator on Android.
The other HP-11C and the PX11C calculators unfortunately cannot communicate with a PC and exchange data, apart from updating the firmware .
the interface
The PH11C interface allows to generate :
either dumps from HP-11C source programs saved in .TXT or .11C files
or HP-11C source programs in .TXT from DM11L dumps saved in file .D11.
The dumps are exchanged with the DM11L using a USB cable and the PuTTY program .
