NAME
  minphys - General: Bounds the data transfer size

SYNOPSIS
  void minphys(

ARGUMENTS

DESCRIPTION
  The minphys interface bounds the data transfer size by checking the
  b_bcount member of the buf structure pointed to by the bp argument.  If the
  b_bcount member is greater than 63 * 1024, minphys sets b_bcount to 63 *
  1024.

RETURN VALUES
  The minphys interface does not return a value. However, it may change the
  contents of the b_bcount member of the buf structure.
