Resetting the Reader NF BC Booting and Resetting the Reader Resetting the reader can involve forcing the reader to turn off, or stopping applications and clearing the reader’s conventional memory. 9 Note: Turning off the reader by pressing does not clear the reader’s conventional memory. When you turn the reader back on, it resumes operating just as it was before you put it in Suspend mode. Forcing the Reader to Turn Off If the reader will not turn off when you press , you can force the reader to turn off by pressing - -. It may take a few seconds before the reader turns off. Later, when you press to turn the reader on, the Boot Loader menu appears. From the menu, you can dump the contents of conventional memory to another computer and/or you can cold boot the reader. For help, see “Dumping the Reader’s 640K Conventional Memory” later in this chapter, and then see “Cold Booting the Reader” earlier in this chapter. Breaking Out of an Application If the application you are running becomes locked in an infinite loop, you can break out of that application without cold booting. The procedure involves setting a flag, called the application break bit, in the reader. Applications check the application break bit when you turn on the reader to determine if they should resume running. If the bit is set to 1, the programs will not resume. IRL applications automatically check the application break bit. If you are creating your own applications in C or Basic, you should make each application check this bit every time the reader is turned on. See your JANUS PSK reference manual to learn how to check the application bit. Note: If your C or Basic application is locked in an infinite loop and does not check the application bit, you can cold boot the reader to break out of the application. 9-5
JANUS 2020 Hand-Held Computer User’s Manual (4MB) NF BC 9-6 To break out of an application 1. Press to turn off the reader. If you must force the reader to turn off, see the previous section. 2. Press - -. 3. Press to set the application break bit in the reader. 4. Press to turn on the reader. If the application checks the application break bit, it should take appropriate action when it detects that the bit has been set. If the application does not check the application break bit, it will resume running. You may have to cold boot the reader to break out of this application. For help, see “Cold Booting the Reader” earlier in this chapter. Displaying the Boot Loader Menu The Boot Loader menu appears when you enter a designated key combination, the system flash is corrupt, the BIOS checksums fail, or the reader cannot resume. From the Boot Loader menu, you can perform advanced reader commands, as described later in this section. To display the Boot Loader menu 1. Press to turn off the reader. 2. Press - -. 3. Press . 4. Press to turn on the reader. If you do not press a key within 60 seconds after a screen is displayed, the reader automatically shuts off and you have to start over at Step 1. 5. The reader may prompt you for a password. If so, you must enter the password before you can display the Boot Loader menu. Type the password. You are allowed three attempts to type the password correctly. If you fail, the reader does not display the Boot Loader menu. Instead, the reader resumes normal operation. Note: The reader comes from the factory with the password disabled.
