¿ Resucitas un hilo de hace 18 años solamente para eso ?
Yo he encontrado una respuesta en 1 minuto:
4690 supports applications written in IBM 4680 BASIC (a variant of CBASIC), Metaware High-C, and Java 2. The Java language-based ability at both the server and the client, along with the extension of TCP/IP ability to the client, enables Java applications at both the server and client to run concurrently with existing CBASIC or C applications. Users can make functional enhancements to existing applications by developing a new Java application that communicates with an existing application.
