63 .It te%d: no write ring.
64 An attempt was made to write on the tape drive
65 when no write ring was present; this message is written on the terminal of
66 the user who tried to access the tape.
69 An attempt was made to access the tape while it
70 was offline; this message is written on the terminal of the user
71 who tried to access the tape.
73 .It te%d: can't change density in mid-tape.
74 An attempt was made to write
75 on a tape at a different density than is already recorded on the tape.

79 .It te%d: hard error bn%d er=%b.
83 the tm error register is
84 printed in octal with the bits symbolically decoded. Any error is
85 fatal on non-raw tape; when possible the driver will have retried
86 the operation which failed several times before reporting the error.
88 .It te%d: lost interrupt.
89 A tape operation did not complete
90 within a reasonable time, most likely because the tape was taken
91 off-line during rewind or lost vacuum. The controller should, but does not,
92 give an interrupt in these cases. The device will be made available
93 again after this message, but any current open reference to the device
94 will return an error as the operation in progress aborts.
110 May hang if a physical (non-data) error occurs.
