VT 100 Menu Support
When connected to an asynchronous VT 100 terminal or VT 100
terminal emulator, use the built-in ISU 2x64 menu system for
configuration of both DTE ports. The VT 100 screens can be acti-
vated by typing
AT!V
while connected to either DTE port (in AT
command mode), or by typing
!V
at the prompt while using the
maintenance port. The maintenance port is an asynchronous port
always set to 9600 bps, 8 data bits, one stop bit, no parity, and no
flow control. By using the VT 100 screens on the maintenance
port, both DTE ports can be configured from one terminal. The
command
Ctrl+P
switches between DTE #1 and DTE #2.
GETTING STARTED
At power up, the ISU 2x64 runs a self test as indicated on the dis-
play. After approximately 10 seconds,
Passed
is momentarily dis-
played (if the ISU 2x64 does not pass the self test, see If Self Test
Fails on page 77). This is followed by the
Current Status
mode of
DTE#1
. The
Current Status
mode
DTE#2
is shown by pressing
either arrow key. This is the recommended resting place for the
unit since it shows the current operational status of the unit. For
instance, if the ISU 2x64 is not connected to the network, the Cur-
rent Status menu displays
ISU 2x64 DTE# (1 or 2) Link down
. If
the unit is connected to the network and functioning properly, it
displays
ISU 2x64 DTE# (1 or 2) Ready
. A list of Current Status
messages is provided in Current Status Messages on page 95.
Pressing the
Cancel
key repeatedly returns the unit to the Cur-
rent Status menu. While at the Current Status menu, pressing
any key, except the
Cancel
and # keys, repeatedly changes the
display to the top of the menu tree. Pressing the # key brings up
the
Dial
submenu. While in a menu tree, pressing the # key
causes the unit to return to the
Current Status
menu.
