-.Sh NAME
-.Nm rmt
-.Nd remote magtape protocol module
-.Sh SYNOPSIS
-.Nm rmt
-.Sh DESCRIPTION
-.Nm Rmt
-is a program used by the remote dump and restore programs
-in manipulating a magnetic tape drive through an interprocess
-communication connection.
-.Nm Rmt
-is normally started up with an
-.Xr rexec 3
-or
-.Xr rcmd 3
-call.
-.Pp
-The
-.Nm rmt
-program accepts requests specific to the manipulation of
-magnetic tapes, performs the commands, then responds with
-a status indication. All responses are in
-.Tn ASCII
-and in
-one of two forms.
-Successful commands have responses of:
-.Bd -filled -offset indent
-.Sm off
-.Sy A Ar number No \en
-.Sm on
-.Ed
-.Pp
-.Ar Number
-is an
-.Tn ASCII
-representation of a decimal number.
-Unsuccessful commands are responded to with:
-.Bd -filled -offset indent
-.Sm off
-.Xo Sy E Ar error-number
-.No \en Ar error-message
-.No \en
-.Xc
-.Sm on
-.Ed
-.Pp
-.Ar Error-number
-is one of the possible error
-numbers described in
-.Xr intro 2
-and
-.Ar error-message
-is the corresponding error string as printed
-from a call to
-.Xr perror 3 .
-The protocol is comprised of the
-following commands, which are sent as indicated - no spaces are supplied
-between the command and its arguments, or between its arguments, and
-.Ql \en
-indicates that a newline should be supplied:
-.Bl -tag -width Ds
-.Sm off
-.It Xo Sy \&O Ar device
-.No \en Ar mode No \en
-.Xc
-Open the specified
-.Ar device
-using the indicated
-.Ar mode .
-.Ar Device
-is a full pathname and
-.Ar mode
-is an
-.Tn ASCII
-representation of a decimal
-number suitable for passing to
-.Xr open 2 .
-If a device had already been opened, it is
-closed before a new open is performed.
-.It Xo Sy C Ar device No \en
-.Xc
-Close the currently open device. The
-.Ar device
-specified is ignored.
-.It Xo Sy L
-.Ar whence No \en
-.Ar offset No \en
-.Xc
-.Sm on
-Perform an
-.Xr lseek 2
-operation using the specified parameters.
-The response value is that returned from the
-.Xr lseek
-call.
-.Sm off
-.It Sy W Ar count No \en
-.Sm on
-Write data onto the open device.
-.Nm Rmt
-reads
-.Ar count
-bytes from the connection, aborting if
-a premature end-of-file is encountered.
-The response value is that returned from
-the
-.Xr write 2
-call.
-.Sm off
-.It Sy R Ar count No \en
-.Sm on
-Read
-.Ar count
-bytes of data from the open device.
-If
-.Ar count
-exceeds the size of the data buffer (10 kilobytes), it is
-truncated to the data buffer size.
-.Nm rmt
-then performs the requested
-.Xr read 2
-and responds with
-.Sm off
-.Sy A Ar count-read No \en
-.Sm on
-if the read was
-successful; otherwise an error in the
-standard format is returned. If the read
-was successful, the data read is then sent.
-.Sm off
-.It Xo Sy I Ar operation
-.No \en Ar count No \en
-.Xc
-.Sm on
-Perform a
-.Dv MTIOCOP
-.Xr ioctl 2
-command using the specified parameters.
-The parameters are interpreted as the
-.Tn ASCII
-representations of the decimal values
-to place in the
-.Ar mt_op
-and
-.Ar mt_count
-fields of the structure used in the
-.Xr ioctl
-call. The return value is the
-.Ar count
-parameter when the operation is successful.
-.It Sy S
-Return the status of the open device, as
-obtained with a
-.Dv MTIOCGET
-.Xr ioctl
-call. If the operation was successful,
-an ``ack'' is sent with the size of the
-status buffer, then the status buffer is
-sent (in binary).
-.El
-.Sm on
-.Pp
-Any other command causes
-.Nm rmt
-to exit.
-.Sh DIAGNOSTICS
-All responses are of the form described above.
-.Sh SEE ALSO
-.Xr rcmd 3 ,
-.Xr rexec 3 ,
-.Xr mtio 4 ,
-.Xr rdump 8 ,
-.Xr rrestore 8
-.Sh BUGS
-People tempted to use this for a remote file access protocol
-are discouraged.
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.2 .
