TS(4)               UNIX Programmer's Manual                TS(4)

NAME
     ts - TS-11 magtape interface

DESCRIPTION
     The TS-11 combination provides a standard tape drive inter-
     face as described in _m_t(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), ht(4), mt(4), tm(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 termi-
     nal of the user who tried to access the tape.

     ts%d: hard error bn%d xs0=%b xs1=%b xs2=%b xs3=%b.  A hard
     error occurred on the tape at block _b_n; status register 0-3
     are printed in octal and symbolically decoded as bits.

     ts%d: addr mod 4 != 0.  The address of a TS-11 command
     packet was not on an even longword boundary.

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

     The device has the same register addresses as a TM-11.  See
     _t_m(4).

     The system should remember which controlling terminal has
     the tape drive open and write error messages to that termi-
     nal rather than on the console.
