The xts command is a debugging tool for the
driver. It performs an XTIOCSTATSioctl(S)
call on its standard input file to extract the accumulated statistics
for the attached group of channels.
This call will fail if statistics have not been configured in the
driver, or the standard input is not attached to a
channel. The statistics are printed one item per line on the standard output.
Causes a ``formfeed'' character to be put out at the
end of the output for the benefit of page-display programs.
Returns 0 upon successful completion; 1 otherwise.
