                     15: .SH DESCRIPTION
                     16: The tm-03/transport combination provides a standard tape drive
                     17: interface as described in
                     18: .IR mtio (4).
                     19: All drives provide both 800 and 1600 bpi; the TE-16 runs at 45 ips,
                     20: the TU-45 at 75 ips, while the TU-77 runs at 125 ips and autoloads tapes.

                     31: \fBtu%d: no write ring\fR.  An attempt was made to write on the tape drive
                     32: when no write ring was present; this message is written on the terminal of
                     33: the user who tried to access the tape.
                     34: .PP
                     35: \fBtu%d: not online\fR.  An attempt was made to access the tape while it
                     36: was offline; this message is written on the terminal of the user
                     37: who tried to access the tape.
                     38: .PP
                     39: \fBtu%d: can't change density in mid-tape\fR.  An attempt was made to write
                     40: on a tape at a different density than is already recorded on the tape.
                     41: This message is written on the terminal of the user who tried to switch
                     42: the density.

                     44: \fBtu%d: hard error bn%d mbsr=%b er=%b ds=%b\fR.   A tape error occurred
                     45: at block \fIbn\fR; the ht error register and drive status register are
                     46: printed in octal with the bits symbolically decoded.  Any error is
                     47: fatal on non-raw tape; when possible the driver will have retried
                     48: the operation which failed several times before reporting the error.
                     49: .SH BUGS
                     50: If any non-data error is encountered on non-raw tape, it refuses to do anything
                     51: more until closed.
