1.7 *C MODE -- SECURITY

The *C Mode is used to block access to the user's program information and certain CR10 functions. There are 3 levels of security, each with its own 4 digit password. All passwords are set to 0000 on power-up which disables security (unless the CR10 has a custom PROM with the password built in). Setting a password to a non-zero value "locks" the functions secured at that level. The password must subsequently be entered to temporarily unlock security through that level. Passwords are stored in write protected memory and affect the program signature.

When security is disabled, *C will advance directly to the window containing the first password. A non-zero password must be entered in order to advance to the next window. Leaving a password 0, or entering 0 for the password disables that and subsequent levels of security.

Security may be temporarily disabled by entering a password in the *C Mode or using the telecommunications L command (Section 5.1). The password entered determines what operations are unlocked (e.g., entering password 2 unlocks the functions secured by passwords 2 and 3). Password 1 (everything

unlocked) must be entered before any passwords can be altered.

When security is temporarily disabled in the *C Mode, entering *0 will automatically re-enable security to the level determined by the passwords entered.

The telecommunications L command temporarily changes the security level. After hanging up, security is reset.

1.8*D MODE -- SAVE OR LOAD PROGRAM

The *D Mode is used with Storage Module, computer/printer to save or load the user's program information (the *1, *2, *3, *A, *C, and *B Modes).

GraphTerm or TERM (PC208 software) automatically make use of the *D Mode to upload and download programs from a computer.

When "*D" is keyed in, the CR10 will display "13:00". A command (Table 1.8-1) is entered by keying the command number and "A".
