A–Answer a call
Use the answer command to answer a call.
AT–Attention
The AT command issued by itself is used to enter command mode. AT is also the prefix for all of the other commands. For example, issue the dial command by typing ATD.
B–Use a specific code and speed (The default is ATB0)
The B command controls the code and baud rate your Intele–Modem uses to communicate. If you want to specify ASCII or Baudot code and the baud rate, type ATB and a number from 0 to
4.What each number means is listed below:
ATB0–Auto search. When your Intele–Modem answers a call, it automatically searches the incoming signals to determine what code to use. If it hears an ASCII signal, it stays in ASCII code at 300 baud. If it doesn’t hear an ASCII signal, the modem switches automatically to Baudot code at 45 baud.
Note that while Auto search can switch codes automatically, it cannot switch speeds. If a caller uses 110-baud ASCII code, use the ATB4 command to switch your modem to 110 baud. Similarly, if you get a call in Baudot code at 50 baud, use the ATB2 command to match speeds.
B1–Baudot code, 45 baud. Use this setting for making calls to TTYs in the United States and other countries which use 45-baud Baudot code.
B2–Baudot code, 50 baud. Use this setting for making calls to TTYs in countries that use 50-baud Baudot code.
B3–ASCII code, 300 baud. Use this setting to make calls to computers and 300-baud ASCII TTYs.
B4–ASCII code, 110 baud. Use this setting for making calls to 110-baud ASCII TTYs.
D–Dial telephone
Type AT followed by D to dial a phone number from your computer keyboard. Press the Enter Key to dial. For example:
ATD 5551212 [Enter]
You can specify tone or pulse dialing by adding T or P to the command. For example, to tone dial, use:
ATDT 5551212 [Enter]
Type P after ATD to tell your Intele–Modem to pulse dial. For example,
ATDP 5551212 [Enter]
Typing a comma within the phone number causes a two-second pause in dialing. If you’re using your Intele–Modem in an office setting where you need to dial 9 to get an outside line, a pause may be needed to allow time to get a dial tone. Here’s an example:
ATD 9,5551212 [Enter]
You can use as many commas as you need. Each one equals two seconds.
E–Echo (The default is E1)
Echo controls how the commands you type to your modem are displayed on your computer monitor.
E0–Echo off. When you type a Command, it will not be displayed on the computer monitor.
E1–Echo on. Commands are displayed as you type them.
F–Full- or half-duplex (The default is full-duplex)
Full-and half-duplex are two ways that the modem displays what you type on your computer screen.
ATF0–Half-duplex. In half-duplex, your modem sends characters you type to the other computer or TTY and also to your computer screen. If each character you type appears twice on your monitor (HHII TTHHEERREE), change to full-duplex. TTYs that use Baudot code always use half-duplex. See the Problem and Solutions section
