        !            43:      the  following: AAnnyy  (that is,  call  as soon  as a  file is
        !            44:      queued for sending),  WWkk (for Monday through Friday), or one
        !            45:      or  more of  SSuu, MMoo,  TTuu, WWee,  TThh, FFrr,  or SSaa,  separated by
        !            46:      commas   (be   sure    not   to   use   spaces   here).    A
        !            47:      _d_a_y__a_n_d__t_i_m_e__l_i_s_t is  identical to a _d_a_y__l_i_s_t  but appends a
        !            48:      _t_i_m_e field  to one or more of the  days specified.  The _t_i_m_e
        !            49:      field consists of  two four-digit 24-hour times separated by
        !            50:      a hyphen.  The  legal call time is any time  at or after the
        !            51:      first time  and at or before the second  time.  If the first
        !            52:      time is greater than the second time, then the valid calling
        !            53:      times will be from midnight  to the second time and from the
        !            54:      first  time  through  midnight.   Omitting  the  _t_i_m_e  field
        !            55:      permits  calling at  any  time on  the  specified day.   For
        !            56:      example:

        !            94:      This gives the  string that UUCP is to send  to the modem in
        !            95:      order  to call  the remote  site.   This string  may include
        !            96:      special characters for  your modem (e.g., some modems accept
        !            97:      a  comma if  a  pause is  needed during  dialing), but  will
        !            98:      usually be simply the number to dial, e.g.  ``17085590412''.
        !            99:      The string  that is actually  sent to the  modem consists of
        !           100:      the   ccss  and   ddss  strings  from   the  modem's   entry  in
        !           101:      /eettcc/mmooddeemmccaapp, the telephone  number, and finally the ddee and

        !           108: to log  on to the  remote computer.  The chat  script consists of
        !           109: strings of characters to be exchanged between the remote computer
        !           110: and your  UUCP system; first  comes an _e_x_p_e_c_t__s_t_r_i_n_g  (the string

        !           112: to send in response to the _e_x_p_e_c_t__s_t_r_i_n_g).  When calling a remote
        !           113: site, your  computer waits for  a carrier from  the remote modem,
        !           114: then waits for the  first _e_x_p_e_c_t__s_t_r_i_n_g, after which it sends the

        !           161: second simple  _e_x_p_e_c_t__s_t_r_i_n_g; if the  second simple _e_x_p_e_c_t__s_t_r_i_n_g
