Supported terminals, access methods, and interfaces
Each terminal category, system interface, and access method has its own
unique operating characteristics such as display formats, keying procedures,
pause and disconnect capabilities, and other special features. Read this
chapter and Chapter 2 for general information, and then refer to the chapters
that describe the your own terminal type, system interface, and access method.
Supported terminals, access methods, and interfaces
Supported access methods
Model 204 provides support for a variety of terminals that use the SNA
Communications Server (formerly VTAM) (Virtual Telecommunications Access
Method)
Supported SNA Communications Server terminals
SNA Communications Server supports the following terminals:
• IBM 3270s and compatible terminals
• IBM 3767 terminals
• Terminal types supported by the IBM Network Terminal Option (NTO)
Supported system interfaces
Model 204 also can be accessed by means of one of the following system
interfaces:
• CICS (as a transaction)
• TSO (as a command processor or as a called program)
• CMS (via the Inter-User Communication Vehicle)
• INTERCOMM (as a subsystem)
Terminal emulators and the LANGUSER parameter
Many different terminal emulators are in existence today. You must ensure that
the terminal emulator you use sends characters to the mainframe that are
compatible with the characters that are defined in the IBM code page for the
particular LANGUSER value set at your site. (See the Model 204 Language
Support Summary.) In the event that certain characters from the your terminal
emulator are not compatible with the IBM code page, you must provide
translation commands for those particular characters. For example, the
terminal emulator hexadecimal code for a particular character must be
translated to the IBM hexadecimal code for the same character.
Note: An underlying problem could appear if you store incompatible characters
into a Model 204 file using one terminal emulator and attempt to retrieve them
