HT(4) UNIX Programmer's Manual HT(4) NAME ht - TM-03/TE-16,TU-45,TU-77 magtape interface DESCRIPTION The TM-03/transport combination provides a standard tape drive interface as described in _m_t(4). All drives provide both 800 and 1600 bpi; the TE-16 runs at 45 ips, the TU-45 at 75 ips, while the TU-77 runs at 125 ips and autoloads tapes. SEE ALSO mt(1), tar(1), tp(1), mt(4), tm(4), ts(4) DIAGNOSTICS tu%d: no write ring. 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. tu%d: not online. An attempt was made to access the tape while it was offline; this message is written on the termi- nal of the user who tried to access the tape. tu%d: can't switch density in mid-tape. An attempt was made to write on a tape at a different density than is already recorded on the tape. This message is written on the termi- nal of the user who tried to switch the density. tu%d: hard error bn%d er=%b ds=%b. A tape error occurred at block _b_n; the ht error register and drive status register are printed in octal with the bits symbolically decoded. Any error is fatal on non-raw tape; when possible the driver will have retried the operation which failed several times before reporting the error. BUGS If any non-data error is encountered on non-raw tape, it refuses to do anything more until closed. The system should remember which controlling terminal has the tape drive open and write error messages to that termi- nal rather than on the console. Printed 5/17/83 1
