Overview

This chapter describes the client capabilities of Sun MTP Client, the supported protocols, and the operating requirements.


Capabilities of Sun MTP Client

Sun MTP Client provides the following client capabilities:

These capabilities allow a user to connect a terminal or printer, EPI application or ECI application running on a PC or UNIX machine, directly into one or more Sun MTP server systems running on one or more UNIX machines. In addition, Sun MTP Client provides examples that you can use for ideas when creating your own applications.

Each Sun MTP Client in FIGURE 1-1 can support multiple ECI applications, EPI applications, and 3270 Terminals or Printers as shown in FIGURE 1-2.

Supported Transport Protocols

This section describes how Sun MTP Client supports connection to Sun MTP via TCP/IP and SNA.

TCP/IP

Sun MTP Client supports the TCP/IP protocol. It is available for Solaris and Windows versions.

On Windows, it is implemented by any WINSOCK compliant sockets Dynamic Linked Library (DLL). Chapter 2, describes the method used by Sun MTP Client to determine the version of the DLL it uses, if more than one implementation is installed on your PC.

On Solaris, TCP/IP is part of the operating system.

SNA

Connection from Sun MTP Client for Windows to Sun MTP is supported using either the Microsoft SNA Server or IBM Communications Server. This requires a machine running the Windows Server and the SNA Server that has an LU 6.2 connection configured to each Sun MTP Client region to which access is required. Then you can connect Sun MTP Client for Windows to Sun MTP from one or more Windows machines via the SNA Server (See FIGURE 5-3). Each machine running Sun MTP Client must also have the SNA Client software installed.

Connection between each SNA Client and the SNA Server is achieved using a number of alternatives. For more details, see the documentation for your SNA Server.

SNA is not currently supported for Sun MTP Client on Solaris.


Operating Requirements

Sun MTP Client is available on several platforms. Following are the minimum operating requirements:
