1.2.2 Supported Software The software used with this terminal can be divided into two categories: the system software that includes the BIOS, OS, and device drivers and the user software such as the development tools. The system software is stored on the DINOR FLASH ROM (1 MB), and the user software is supported from the SDK CD-ROM (version 4.0) supplied by Casio at free of charge. The following paragraphs describe the software. BIOS The BIOS program is stored in the DINOR FLASH ROM. 256 KB of

1.3 Precautions If reading the internal clock with INT21h the significant data should include and be limited to the seconds digits. On this terminal the time is read directly from the RTC so that the correct time can be attained at any moment, even during extended continuous use. As a result the 1/100 of a second digit is ignored. (refer to Chapter 6.3 “Clock Control Driver”) If it is necessary to reboot the system from an application, use the dedicated system library. However, the reboo

This system will not execute an alarm indication for an LB2 event (low sub-battery voltage) or LB3 event (low SRAM card battery voltage). Therefore, the application program side must acquire the alarm status via the system library and display an appropriate alarm message. If the volume of the buzzer is set to zero by the System Menu or system library, the LB1 (low main battery voltage) alarm will not be heard. Also, other sounds issued by the system will be inaudible. If the system is boot

Do not input “^P” from the DOS prompt. If it is input, “^P” requests DOS to redirect console output to printer. However, the IT-2000 does not have the printer being installed, it will enter into wait mode. For more information about the system library refer to Chapter 7.6.2 “System Library”. Also, refer to Chapter 2.2.4 “Battery Voltage Monitoring Process” for information about the low-battery voltage notification function. 14
