WP-34S: Safely copy a graphics register's contents

[Marcus von Cube]

You need to link your calculator to the emulator. The classic Windows emulator has an ini file (wp34s.ini) in its working directory which names the COM port e. g. COM1: on a single line. The Qt emulators have a menu option for this.

Now go to P.FCN, RECV on the emulator and P.FCN, SENDA on the calculator. The latter sends the contents of RAM to the former. You should see a success message on both screens.

Is your calculator equipped with the crystal and is it active? If yes skip this paragraph, if not enter a percentage in the X register of the calculator (only there!) to adjust the transmission speed before you call the SENDA command. Start with 90 and go up slowly until the transfer works. (This is the number you should note on the back of your calculator because you will need it for each transfer; only whole numbers are supported.)

After a successful transfer both calculators (device and emulator) should have the same status and programs. Quit the emulator and post the wp34s.dat file here. The file is in the emulator's working directory (classic emulator) or in your personal settings folder for the Qt emulators. If you do not want to overwrite the emulator's RAM image, just make a copy of this file before the transfer.
