46 combination provides a standard tape drive

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

78 the mt error register and drive status register are
79 printed in octal with the bits symbolically decoded. Any error is
80 fatal on non-raw tape; when possible the driver will have retried
81 the operation which failed several times before reporting the error.
84 An attempt was made to read a blank tape (a tape without even
88 During an i/o operation the device was set offline. If a
89 non-raw tape was used in the access it is closed.
104 If a physical error (non-data) occurs,
106 may hang ungracefully.
110 tapes are not supported, the numbering of minor devices
111 is inconsistent with triple-density tape units.
112 Unit 0 is drive 0, 1600
