.SH DESCRIPTION
.I osContSetCh
specifies 
.I ch
number of controllers for the system to read from. By default, the 
system polls all 
.I MAXCONTROLLERS
controllers to read data.
By setting 
.I ch
to a smaller number than
.I MAXCONTROLLERS,
one can save time in polling for controller data.
.I ch
cannot be greater than 
.I MAXCONTROLLERS.
