TM(IV)                      10/15/73                       TM(IV)







NAME

     tm - TM-11/TU-10 magtape interface



DESCRIPTION

     The files mt0, ..., mt7 refer to the DEC TU10/TM11  magtape.

     When  opened for reading or writing, the magtape is rewound.

     A tape consists of a series of 512 byte  records  terminated

     by  an  end-of-file.   When  the  magtape  is  closed  after

     writing, an end-of-file is written.



     The magtape can only be opened once at any instant.



FILES

     /dev/mt?



SEE ALSO

     tp(I)



BUGS

     If you hit the EOF mark or  get  other  non-data  errors  it

     refuses  to  do anything more until closed.  There has to be

     some reasonable way to deal with multi-file tapes.
