       1.  _N_e_w__C_o_m_m_a_n_d_s


       Several changes have been made to the functionality and pro-
       gramming of the TVS701B with revision 16. One is a the abil-
       ity to perform 71/72 (temporary link access) on downward
       transitions of input bit 0 respectively. The ROM dump capa-
       bility has been deleted.  The default value of the response
       timer is now 400 milliseconds. The site ID can now be either
       one or two digits. The watch dog timer has been made more
       robust.

       All new commands require control priviledges (level 1).


       1.1  _7_5_,__7_6__-__A_u_t_o__T_e_m_p_o_r_a_r_y__O_n_-_L_i_n_k

       If "75" is issued, input 0 acquires additional functional-
       ity, controlling the "temporary link enabled" state of the
       system. If input 0 goes low, the system will change modes as
       if the "71" command had been issued. This feature is
       intended to allow an auxiliary device, such as a CTCSS
       decode, to controltemporary link access. If "76" is issued,
       this feature is disabled.
