ON).
12. Reset String: If necessary, this item can be used to redefine the modem reset
string. (Up to 16 characters: default is ATZ.)
13. Custom Initialization String: This item is used to “customize” the Secure Rack
Modem’s modem initialization string. During configuration, the unit will
build an initialization string based on items selected from the modem
parameters menu. This string will consist of three components: (1) the
default string header (AT&C1&D2), (2) the responses to items 1 through 11
in the Modem Parameters menu, and (3) any special AT commands entered
via item 13. For a listing of available AT commands, please refer to
Chapter 9
.
(Up to 16 characters: default is “undefined”.)
14. Hang-Up String: This item is used to define tasks that are performed after
the Secure Rack Modem hangs up at the end of a communication session.
Typically, the hang-up string would be used to clear memory, or reset the
modem to a set of user-defined parameters. To define the hang-up string,
simply key in the appropriate AT commands for the desired operation(s).
For a listing of available AT commands, please refer to
Chapter 9
. (Up to
16 characters: default is “undefined”.)
When you have finished selecting modem configuration parameters, press
[Esc]
to
return to the main Help screen. User-selected parameters will be saved in the
modem’s non-volatile memory.
5.4 Save Parameters
After you’ve completely configured the unit, save configuration parameters to an
ASCII file as described in
Chapter 8
. This allows quick recovery if the unit is reset
to default parameters, or if configuration is accidentally deleted or altered.
