내장형 시스템의 실시간 운영체제(RTOS)에서는 메모리와 CPU 속도 등의 제한적인 환경에서 원하는 기능을 최적으로 최단시간에 구현할 수 있는 개방형 개발도구 환경이 요구된다. 이러한 개방형 개발환경에는 타겟 시스템에 최소의 부담을 주면서 사용자가 편리하게 원하는 정보를 원격지에서 대화식으로 빠르게 접근, 참조, 제어 할 수 있는 원격 대화형 쉘이 필수적이다. 본 논문에서는 원격지에서 모듈별 로딩, 태스크의 스폰과 더불어 태스크 상태 등을 확인할 수 있는 원격 대화형 쉘 프로그램의 설계와 그에 대한 구현방법을 기술하고 원격지에서 타겟의 부담을 최소화하여 실시간 운영체계에서 정보접근이 용이하고 유지보수가 쉬운 개발환경이 가능하도록 하였다. 이 대화형 쉘은 Q-PLUS RTOS와 연동되어 작동하며 ARM계열의 EBSA285 타겟보드와 NT 호스트상에서 구현, 테스트되었다.
