This tight integration between message passing and CPU scheduling is one of the key mechanisms that makes QNX message passing broadly usable. Thus, sending a message to another process and waiting for a reply does not result in 'losing one's turn' for the CPU. If the receiving process is waiting for the message, control of the CPU is transferred at the same time, without a pass through the CPU scheduler. The message is copied, by the kernel, from the address space of the sending process to that of the receiving process. This is a single operation, called MsgSend.

QNX interprocess communication consists of sending a message from one process to another and waiting for a reply. The system garnered a reputation for reliability and found itself in use running machinery in a number of industrial applications. Over the years QNX was used mostly for 'larger' projects, as its 44k kernel was too large to fit inside the single-chip computers of the era.

In 1984 Quantum Software Systems renamed QUNIX to QNX in an effort to avoid any trademark infringement challenges.One of the first widespread uses of the QNX real-time OS (RTOS) was in the non-embedded world when it was selected as the operating system for the Ontario education system's own computer design, the Unisys ICON. In 1982, the first version of QUNIX was released for the Intel 8088CPU. Both were convinced there was a commercial need for such a system, and moved to the high-tech planned community Kanata, Ontario, to start Quantum Software Systems that year. Gordon Bell and Dan Dodge, both students at the University of Waterloo in 1980, took a course (CS452) in real-time operating systems, in which the students constructed a basic real-time microkernel and user programs.
