- +o The Classing Engine is a SunSoft database used for
- typing information (for example, given a file, what
- type is it, what icon is used for this type?). This is
- used in Sun OpenWindows, and is not part of ToolTalk.
- Some of the ToolTalk commands have options that use the
- Classing Engine in the SunSoft implementation. The
- Classing Engine options are not supported in the
- Silicon Graphics (SGI) implementation.
-
- +o The SunSoft implementation of ToolTalk supports a _d_e_s
- authentication option and uses secure RPC. This is not
- supported in the SGI ToolTalk implementation.
-
- +o The SunSoft implementation of ToolTalk supports
- _i_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n of error/warning messages. This is
- not supported in the SGI ToolTalk implementation. The
- error message strings can be found in Appendix C of the
- _T_o_o_l_T_a_l_k _P_r_o_g_r_a_m_m_e_r'_s _G_u_i_d_e (available as part of the
- ToolTalk Development option).

-
- +o The SunSoft implementation of ToolTalk has a program
- named _t_t_c_p for copying files containing ToolTalk
- objects. In SGI's implementation, _t_t_c_p is a test
- program for TCP and UDP performance. The SunSoft
- ToolTalk _t_t_c_p command has been renamed _t_t_c_o_p_y in SGI
- ToolTalk.

- a ToolTalk client process connects to a default ToolTalk
- message server (ttsession). Silicon Graphics has modified
- the default behavior to include the concept of the
- CASEVision/ClearCase _v_i_e_w. By default, if ToolTalk clients
- are running in a CASEVision/ClearCase _v_i_e_w, the ttsession
- will be started in the _v_i_e_w and dedicated only to processes
- in the _v_i_e_w. This overrides the SunSoft ToolTalk default
- mechanism. If the ToolTalk client is not running in a
- CASEVision/ClearCase _v_i_e_w, it connects to the ttsession in
- the same manner as in the SunSoft ToolTalk implementation.
- (See CASEVision/ClearCase for details on what it means to be
- in a _v_i_e_w).

-
- +o ToolTalk 1.4 supports all previous ToolTalk protocols
- and the ToolTalk 1.4(SunSoft 1.2) protocol, thus
- preserving the ability for older ToolTalk clients to
- communicate with a version 1.4 ttsession server and
- also allowing new 1.4 clients to communicate with the
- same server.
