VT 100 TERMINAL MENU SUPPORT
When connected to an asynchronous VT 100 terminal or VT 100 terminal em-
ulator, use the built-in ISU 128 menu system for configuration. To enter into
the menus, type AT!V Enter. To go to a particular menu, simply press the hot
keys for that menu. The main branches of the menu tree and their hot keys are:
• STATUS (Ctl-V)
• TEST (Ctl-T)
• CONFIG (Ctl-C)
• DIAL (Ctl-D)
Status Screen
To determine the current status of the unit, press Ctrl+V to access the Status
Screen (see Figure 4-1). The Status Screen displays unit information such as
the loop status, software revision, the result of the initial self test, and the sta-
tus buffer messages. The most recent message always displays as Status Buff-
er 1. An explanation of status buffer messages can be found in the appendix
Status Buffer Messages.
