Example 3:
Define  a  2501  card  reader  device  on  device  address  000C.  The  card  reader  is  a  socket  device  accepting  
remote  connections  from  address  127.0.0.1  port  2501.  The  file  contains  variable  length  lines  of  ASCII  
characters  delimited  by  line  feed  or  carriage  return  line  feed  sequences  at  the  end  of  each  line.  Lines  
longer  than  80  bytes  have  to  be  truncated  and  a  unit  exception  status  has  to  be  presented  after  reading  
the  last  card  in  the  file.
