                     16: The tm-11/te-10 combination provides a standard tape drive
                     17: interface as described in
                     18: .IR mtio (4).
                     19: Hardware implementing this on the VAX is typified by the Emulex TC-11
                     20: controller operating with a Kennedy model 9300 tape transport,
                     21: providing 800 and 1600 bpi operation at 125 ips.

                     32: \fBte%d: no write ring\fR.  An attempt was made to write on the tape drive
                     33: when no write ring was present; this message is written on the terminal of
                     34: the user who tried to access the tape.
                     35: .PP
                     36: \fBte%d: not online\fR.  An attempt was made to access the tape while it
                     37: was offline; this message is written on the terminal of the user
                     38: who tried to access the tape.
                     39: .PP
                     40: \fBte%d: can't change density in mid-tape\fR.  An attempt was made to write
                     41: on a tape at a different density than is already recorded on the tape.
                     42: This message is written on the terminal of the user who tried to switch
                     43: the density.
                     44: .PP
                     45: \fBte%d: hard error bn%d er=%b\fR.   A tape error occurred
                     46: at block \fIbn\fR; the tm error register is
                     47: printed in octal with the bits symbolically decoded.  Any error is
                     48: fatal on non-raw tape; when possible the driver will have retried
                     49: the operation which failed several times before reporting the error.
                     50: .PP
                     51: \fBte%d: lost interrupt\fR.  A tape operation did not complete
                     52: within a reasonable time, most likely because the tape was taken
                     53: off-line during rewind or lost vacuum.  The controller should, but does not,
                     54: give an interrupt in these cases.  The device will be made available
                     55: again after this message, but any current open reference to the device
                     56: will return an error as the operation in progress aborts.
                     57: .SH BUGS
                     58: If any non-data error is encountered on non-raw tape, it refuses to do anything
                     59: more until closed.
