VAX-based graphics mail system

Conference ·
OSTI ID:6101449
Graphics messages (freehand drawings, text, and symbols) can be interactively created using an intelligent graphics terminal (Tektronix 4115B) and selectively sent to other graphics terminals for display, editing, and return transmission. This VAX-based program is run as several detached process to handle the message routing. Inter-process communication is achieved with VMS mailboxes and asynchronous software traps (AST's) are utilized for all input in order to maintain low system overhead and fast, asynchronous response.
