        !            14: kermit allows the user to communicate with a remote computer sys-
        !            15: tem and  to transfer files between the  local and remote systems.
        !            16: kermit can transfer ASCII or binary files of any length in either
        !            17: direction.  The two computers must be able to contact each other,
        !            18: such as through a serial line  or by modem over a telephone line,
        !            19: and both systems must  have kkeerrmmiitt available.  The user must have
        !            20: login privileges  on both systems and  appropriate permissions in
        !            21: directories used for file transfer.
        !            22: 
        !            23: The kermit command line specifies a mode, followed without inter-

        !            25: arguments and files.  The three possible modes are as follows:

        !            27: 
        !            28:      cc       Connect the two systems so they can communicate
        !            29:      rr       Receive files from the other system
        !            30:      ss       Send each _f_i_l_e to the other system.
        !            31: 
        !            32: 
        !            33: kermit normally  uses a default  communication line at  a default
        !            34: baud rate; the defaults vary from system to system.  kermit norm-
        !            35: ally strips  leading directory information from  the path name of
        !            36: each file it  sends and converts the name to  upper case; it con-
        !            37: verts the file name to lower case when receiving.
        !            38: 
        !            39: The following flags modify kkeerrmmiitt's normal behavior.
        !            40: 
        !            41: aa       Specify  complete path  names for  sending  and receiving
        !            42:         files.  Used only with s mode.   The a flag requires file

        !            44:         receiving file.  For example, the command
        !            45: 
        !            46:                 kermit sa /usr/joe/stuff.c /usr/tom/src/thing.c
        !            47: 
        !            48:         sends the file /usr/joe/stuff.c but specifies its name as
        !            49:         /usr/tom/src/thing.c for the receiving  system.  The tar-
        !            50:         get directory must exist on the  receiving system.  The a
        !            51:         flag implies  the  use of  the  f and  x flags  described
        !            52:         below.

        !            85:

        !            87:         for each character; this is  necessary to transfer binary
        !            88:         (non-ASCII) files.  If you use i  flag when sending, also
        !            89:         use it on the receiving system.

        !            93: ll _l_i_n_e  Use line.  For example, the command

        !            95: 
        !            96:         tells kermit to  use line tty50  at 1200 baud  instead of

        !            98: 
        !            99: mm       Macintosh mode.  Necessary when sending files to an Apple
        !           100:         Macintosh; used only with s mode.
        !           101: 
        !           102: tt        Tymnet  mode.   Allows  Tymnet  to  keep  up  with  file

        !           104: 
        !           105: xx       Allows the  specification of a complete  pathname for the
        !           106:         receiving file; used only with s  mode.  For example, the
        !           107:         command
        !           108: 
        !           109:                 kermit sx mydir/stuff
        !           110: 
        !           111:         sends  the  file   mydir/stuff  to  mydir/stuff   on  the
        !           112:         receiving system.  The target directory must exist on the
        !           113:         receiving system and the user  must have write permission
        !           114:         in it.
        !           115: 
        !           116: kermit  c recognizes  two escape  sequences.  The  default escape
        !           117: character `^' can be changed with the e flag, as noted above.
        !           118:

        !           142: to connect to the remote system, invoke kermit with the h flag in
        !           143: either  send or  receive  mode on  the remote  system only,  type
        !           144: ``^s'' to  suspend the local kermit c,  and finally invoke kermit
