4. Terminal Operation
Terminal Interface
This chapter describes the screens structure and menu con-
trols for the TxPORT PRISM 3021 terminal interface. The
interface is a firmware application program embedded
inside the unit.
It requires an ANSI-compatible VT100 terminal (ASCII), or
a computer running an ANSI terminal emulation program.
The terminal interface uses ASCII break and escape func-
tions, which are implemented differently with the various
terminal emulation programs.
Screen Components
Terminal interface screens have several components com-
mon to all screens (Figure 4 -3).
