Hello.
I am designing a real-time simulation software with Performer. The rendering
process must handles input devices(It might be a serial port or a TCP/IP
socket). What is the best way to handle them? My experiences say:

1)If the input device is a serial port, a special I/O process is created and
it handles the serial port. Shared memory is used for communicatation between
the rendering process and the I/O process.

2)If the input device is a socket, the UNIX signal SIGIO can be used. This
means that I can handle input data by asynchronous I/O. Of course method 1)
can be used.

BUT I am sorry I have no working-knowledge with Performer... I wonder there
are some SPECIAL METHODS for input handling using Performer. Does anyone know
them? Or is there no special method available?

Thanks in advance
