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.
