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.
