Examples :
 If we suppose that we wish to take the file 'TEST.ARC',
we have to send : YD TEST.ARC
 
 If we suppose that we wish to send the file 'TEST.ARC',
we have to send : YU TEST.ARC
 
 BBS will respond with either :
 
 Bin transfer of TEST.ARC
        or
 Bin receive  of TEST.ARC
 
 After that,you have to use the YAPP protocol.
