How do you get *unbuffered* pipeline I/O from sys commands

[W. Mackeown]

Does anyone know if it is possible to force SunOS v4.0.1 Unix on Sun 3/50's
to do unbuffered pipeline I/O ?  What is wanted is a way to make system
commands send their output through a pipe in unbuffered form, ie. a single
character at a time. "stty +cbreak" obviously won't accomplish this.

Any ideas/suggestions welcomed. Thanks.
