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

.SH DIAGNOSTICS
\fBts%d: no write ring\fP.  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.
.PP
\fBts%d: not online\fP.  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.
.PP
\fBts%d: hard error bn%d xs0=%b xs1=%b xs2=%b xs3=%b\fP.
A hard error occurred on the tape
at block \fIbn\fP; status register 0-3 are printed in octal and symbolically
decoded as bits.
.PP
\fBts%d: addr mod 4 != 0\fP.
The address of a TS-11 command packet was not on an even longword boundary.
.SH BUGS
If any non-data error is encountered on non-raw tape, it refuses to do anything
more until closed.
.PP
The device has the same register addresses as a TM-11.  See
.IR tm (4).
.PP
The system should remember which controlling terminal has the tape drive
open and write error messages to that terminal rather than on the console.
