a Manual answer command
When the

command is entered, the Modem goes
OFF
HOOK
and waits
for the carrier signal. Use this command to begin computer communication
immediately after talking with
a
friend by phone. In this case, one user should
input
A
while the other uses the dial command
D.
Any command placed
after A will not be executed. If you want to execute other commands, insert
the commands before the manual answer command.
Example:
AT
F1
A
(ENTER)
Wake up!
Select full duplex.
Wait for a carrier tone.
D,
d Autodial command
The
D
command sets the Modem to originate a call without using a tele-
phone.
D
can be followed by the dialer codes shown in Table
7.
When used
alone,
D
sets the Modem to auto-originate mode.
