Emulator Features
The EM3270 emulator functions on all Tandem NonStop systems and has a number of
features that makes it both flexible and easy to use:
•
Command interpreter interface. EMCOM is the command interpreter for the
EM3270 emulator. For the system operator or the EM3270 emulator user, EMCOM
provides a set of more than 25 commands that configure, start, and stop the EM3270
emulator processes. You can enter EMCOM commands interactively at a terminal,
within an IN file, or within an OBEY file.
•
Bisynchronous and SNA support. You can use the EM3270 emulator with either a
byte synchronous (bisynchronous) or System Network Architecture (SNA) interface
to the IBM host. Bisynchronous communications can be used with all Tandem
NonStop systems. The EM3270 emulator can use both Tandem’s SNAX/XF
(Systems Network Architecture (SNA) Communications Services/Extended
