    _\bT_\bf_\bt_\bp 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 _\bh_\bo_\bs_\bt may be
    specified on the command line, in which case _\bt_\bf_\bt_\bp uses _\bh_\bo_\bs_\bt
    as the default host for future transfers (see the c\bco\bon\bnn\bne\bec\bct\bt
    command below).

C\bCO\bOM\bMM\bMA\bAN\bND\bDS\bS
    Once _\bt_\bf_\bt_\bp is running, it issues the prompt t\btf\bft\btp\bp>\b> and recog-
    nizes the following commands:

    c\bco\bon\bnn\bne\bec\bct\bt _\bh_\bo_\bs_\bt-_\bn_\ba_\bm_\be [ _\bp_\bo_\br_\bt ]
         Set the _\bh_\bo_\bs_\bt (and optionally _\bp_\bo_\br_\bt) for transfers.  Note
         that the TFTP protocol, unlike the FTP protocol, does
         not maintain connections betweeen transfers; thus, the
         _\bc_\bo_\bn_\bn_\be_\bc_\bt 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 _\bc_\bo_\bn_\bn_\be_\bc_\bt command;
         the remote host can be specified as part of the _\bg_\be_\bt or
         _\bp_\bu_\bt commands.

    m\bmo\bod\bde\be _\bt_\br_\ba_\bn_\bs_\bf_\be_\br-_\bm_\bo_\bd_\be
         Set the mode for transfers; _\bt_\br_\ba_\bn_\bs_\bf_\be_\br-_\bm_\bo_\bd_\be may be one of
         _\ba_\bs_\bc_\bi_\bi or _\bb_\bi_\bn_\ba_\br_\by.  The default is _\ba_\bs_\bc_\bi_\bi.

         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
         _\bh_\bo_\bs_\bt:_\bf_\bi_\bl_\be_\bn_\ba_\bm_\be to specify both a host and filename at
         the same time.  If the latter form is used, the host-
         name specified becomes the default for future
         transfers.  If the remote-directory form is used, the
         remote host is assumed to be a _\bU_\bN_\bI_\bX machine.

         Get a file or set of files from the specified _\bs_\bo_\bu_\br_\bc_\be_\bs.
         _\bS_\bo_\bu_\br_\bc_\be 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 _\bh_\bo_\bs_\bt:_\bf_\bi_\bl_\be_\bn_\ba_\bm_\be to specify both a

         is used, the last hostname specified becomes the
         default for future transfers.

    Because there is no user-login or validation within the _\bT_\bF_\bT_\bP
    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.
