Reset and Configuration
Recall
Two commands are available for recovering from various data
communications problems. You can reset the 7400B Plus and
recall one of two stored profiles as the current configuration. The
form for this command is as follows:
atz
n (
Enter
)
fffffff
bbbbbbb
where n is the number 0 or 1, representing the configuration
profile to be recalled.
A second command allows you to recall the factory-default
configuration if, for instance, you loose track of changes you have
made and need to start over. The form for this command is as
follows:
at&f
(
Enter
)
fffffff
bbbbbbb
ffffffffffffffffffffffffffffffffffffffffffff
