TCOPY(1) BSD General Commands Manual TCOPY(1)NAME
tcopy -- copy and/or verify mag tapes
SYNOPSIS
tcopy [-cvx] [-s maxblk] [src [dest]]
DESCRIPTION
tcopy is designed to copy magnetic tapes. The only assumption made about the tape is that there are two tape marks at the end. tcopy with
only a source tape (/dev/rst0 by default) specified will print information about the sizes of records and tape files. If a destination is
specified a copy will be made of the source tape. The blocking on the destination tape will be identical to that used on the source tape.
Copying a tape will yield the same output as if just printing the sizes.
Options:
-c Copy src to dest and then verify that the two tapes are identical.
-s maxblk
Specify a maximum block size, maxblk.
-v Given the two tapes, and dest verify that they are identical.
-x Output all informational messages to the standard error. This option is useful when dest is /dev/stdout.

The tcopy command appeared in 4.3BSD.

HT(4) Kernel Interfaces Manual HT(4)NAME
ht - TM-03/TE-16,TU-45,TU-77 MASSBUS magtape interface
SYNOPSIS
/sys/conf/SYSTEM:
NHT ht_drives # TE16, TU45, TU77
/etc/dtab:
#Name Unit# Addr Vector Br Handler(s) # Comments
ht ? 172440 224 5 htintr # tu 16 massbus tape
major device number(s):
raw: 6
block: 0
minor device encoding:
bits 0003 specify HT drive
bit 0004 specifies no-rewind operation
bit 0010 specifies 1600BPI recording density instead of 800BPI
DESCRIPTION
The tm-03/transport combination provides a standard tape drive interface as described in mtio(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.
FILES
/dev/MAKEDEV script to create special files
/dev/MAKEDEV.local script to localize special files

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 termi-
nal 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 terminal of the user who
tried to access the tape.
tu%d: can't change 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 terminal 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 bn; 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 terminal rather than on the
console.
