F1–Full-duplex. In full-duplex, your
modem sends the characters you type
only to the other computer or TTY. You
read the characters on your screen
when the other computer or TTY sends
them back. If typed characters do not
appear on your monitor, change your
setting to half-duplex.
H–Hang up
If you want to hang up at any time
during or after a call, use the ATH
Command.
I–Product code
The ATI Command displays a software
revision code.
M–Speaker on/off (The default is M1)
M0–The speaker is always off.
M1–The speaker is on until an ASCII
carrier or a Baudot character is
detected.
M2–The speaker is always on.
N–Sensitivity (The default is N1)
Sensitivity controls how the
Intele–Modem listens to sounds on the
telephone line. If your modem is
having trouble receiving data correctly,
set it to high sensitivity. This is an
Ultratec addition to the standard
command set.
N0–High sensitivity
N1–Normal sensitivity
O–Online
Use this command to return to on-line
mode when you’re in command mode.
Q–Quiet (The default is Q0)
The Quiet command determines
whether or not the modem sends its
response messages to the computer
monitor.
Q0–The modem sends response
messages to your computer monitor.
Q1–Response messages are not sent to
your computer monitor.
Sn?–Value of any S register
Use this command to find out the value
of any of the S registers. For example,
the command ATS1? asks the modem
for the number of times the phone has
rung.
S0–number of rings (The default is
S0=0)
When the modem is in answer mode,
the S0 register tells it how many rings
to listen for before automatically
answering the phone. You can set it for
any number from 0 to 255.
S0=0 is the manual answer mode
(default setting). Your Intele–Modem
will not automatically answer the
telephone when S0 is set to 0. If your
modem is turned on and a call comes
in, it will send the response RING to
your computer monitor. You must use
the command ATA to answer the call.
After you answer, you will read
CONNECT or CONNECT TTY when
communication is established. If your
modem does not establish a connection,
press Escape to hang up and return to
command mode.
S0=1 tells the modem to Auto-Answer
after one (1) ring.
S0=n means Auto-Answer after n
rings.
Setting S0 to any number greater than
0 has the effect of putting it into Auto-
Answer mode. To take the modem out
of Auto-Answer mode, set S0 back to 0.
S1–Ring count
This register is increased each time the
phone rings.
S2–Set escape character (The default is
S2=43, the ASCII number for the +
character)
The escape character is part of the
escape sequence, which puts the
modem in command mode. This is the
escape sequence: Wait until data
transmission has stopped for at least
one second, type the escape character
three times, then wait another second.
Your Intele–Modem will respond with
OK, and you can enter a command.
Use the ATO Command to go back on-
line.
