NAME
       ts - TS-11 magtape interface

SYNOPSIS
       controller zs0 at uba? csr 0172520 vector tsintr
       tape ts0 at zs0 drive 0

DESCRIPTION
       The  ts-11  combination  provides  a  standard  tape drive interface as
       described in mtio(4).  The ts-11 operates only at 1600  bpi,  and  only
       one transport is possible per controller.

SEE ALSO
       mt(1), tar(1), tp(1), mtio(4), ht(4), tm(4), mt(4), ut(4)

DIAGNOSTICS
       ts%d:  no  write  ring.  An attempt was made to write on the tape drive
       when no write ring was present; this message is written on the terminal
       of the user who tried to access the tape.

       ts%d:  not online.  An attempt was made to access the tape while it was
       offline; this message is written on the terminal of the user who  tried
       to access the tape.

       ts%d:  hard  error  bn%d  xs0=%b.  A hard error occurred on the tape at
       block bn; status register  0  is  printed  in  octal  and  symbolically
       decoded as bits.

BUGS
       If  any non-data error is encountered on non-raw tape, it refuses to do
       anything more until closed.

       The device lives at the same address as a tm-11 tm(4); as  it  is  very
       difficult  to  get  this  device to interrupt, a generic system assumes
       that a ts is present whenever no tm-11 exists but the csr responds  and
       a  ts-11  is  configured.   This does no harm as long as a non-existent
       ts-11 is not accessed.
