+.SH NAME
+tftp \- trivial file transfer program
+.SH SYNOPSIS
+.B tftp
+[
+host
+]
+.SH DESCRIPTION
+.I Tftp
+is the user interface to the Internet TFTP
+(Trivial File Transfer Protocol),
+which allows users to transfer files to and from a remote machine.
+The remote
+.I host
+may be specified on the command line, in which case
+.I tftp
+uses
+.I host
+as the default host for future transfers (see the
+.B connect
+command below).
+.SH COMMANDS
+Once
+.I tftp
+is running, it issues the prompt
+.B tftp>
+and recognizes the following commands:
+.TP
+\fBconnect\fP \fIhost-name\fP [ \fIport\fP ]
+Set the
+.I host
+(and optionally
+.IR port )
+for transfers.
+Note that the TFTP protocol, unlike the FTP protocol,
+does not maintain connections betweeen transfers; thus, the
+.I connect
+command does not actually create a connection,
+but merely remembers what host is to be used for transfers.
+You do not have to use the 
+.I connect
+command; the remote host can be specified as part of the
+.I get
+or
+.I put
+commands.
+.TP
+\fBmode\fP \fItransfer-mode\fP
+Set the mode for transfers; 
+.I transfer-mode
+may be one of
+.IR ascii
+or
+.IR binary .
+The default is
+.IR ascii .
+.TP
+\fBput\fP \fIfile\fP
+.ns
+.TP
+\fBput\fP \fIlocalfile remotefile\fP
+.ns
+.TP
+\fBput\fP \fIfile1 file2 ... fileN remote-directory\fP
+Put a file or set of files to the specified
+remote file or directory.
+The destination
+can be in one of two forms:
+a filename on the remote host, if the host has already been specified,
+or a string of the form
+.I host:filename
+to specify both a host and filename at the same time.
+If the latter form is used,
+the hostname specified becomes the default for future transfers.
+If the remote-directory form is used, the remote host is
+assumed to be a
+.I UNIX
+machine.
+.TP
+\fBget\fP \fIfilename\fP
+.ns
+.TP
+\fBget\fP \fIremotename\fP \fIlocalname\fP
+.ns
+.TP
+\fBget\fP \fIfile1\fP \fIfile2\fP ... \fIfileN\fP
+Get a file or set of files from the specified
+.IR sources .
+.I Source
+can be in one of two forms:
+a filename on the remote host, if the host has already been specified,
+or a string of the form
+.I host:filename
+to specify both a host and filename at the same time.
+If the latter form is used,
+the last hostname specified becomes the default for future transfers.
+.TP
+.B quit
+Exit
+.IR tftp .
+An end of file also exits.
+.TP
+.B verbose
+Toggle verbose mode.
+.TP
+.B trace
+Toggle packet tracing.
+.TP
+.B status
+Show current status.
+.TP
+\fBrexmt\fP \fIretransmission-timeout\fP
+Set the per-packet retransmission timeout, in seconds.
+.TP
+\fBtimeout\fP \fItotal-transmission-timeout\fP
+Set the total transmission timeout, in seconds.
+.TP
+.B ascii
+Shorthand for "mode ascii"
+.TP
+.B binary
+Shorthand for "mode binary"
+.TP
+\fBblocksize\fP \fItransfer-blocksize\fP
+Set the blocksize that is used for transfers. This assumes that the
+server knows about RFC1782 and RFC1783 extensions to the TFTP
+protocol; automatic fallback is supported and will result in a default
+blocksize of 512 octets.
+.TP
+\fB?\fP \ [ \fIcommand-name\fP ... ]
+Print help information.
+.SH BUGS
+.PP
+Because there is no user-login or validation within
+the
+.I TFTP
+protocol, the remote site will probably have some
+sort of file-access restrictions in place.  The
+exact methods are specific to each site and therefore
+difficult to document here.
