Working with Flash
Memory
The Courier V.Everything modem permanently stores three configuratio
"templates," or prepared sets of commands, in Flash memory. You can
use the &Fn command to load one of the three configuration templates
from Flash memory into current memory.
Example: Sending
AT&F1
to your modem will load the Hardware Flow
Control Template into RAM Memory.
DIP switch settings override AT commands at power-on. You can set DIP
switch 10 to ON and reset the Courier V.Everything modem to load the
&F0 settings.
All of the settings in each template are given in Appendix C, Flow Control
Template s .
