modem callback
Use modem callback to enable callback.
Use undo modem callback to disable callback.
Syntax
modem callback
undo modem callback
Default
Callback is disabled.
Views
System view
Predefined user roles
network-admin
Usage guidelines
The callback function enables a modem to disconnect an incoming call and call back the calling party upon request.
Examples
# Enable the callback function.
<Sysname> system-view
[Sysname] modem callback
sendat
Use sendat to issue an AT command to a modem.
Syntax
sendat at-string
Views
Interface view
Predefined user roles
network-admin
Parameters
at-string: Specifies an AT command, a case-insensitive string of 1 to 300 characters. The router automatically converts lowercase characters to uppercase when it sends the command to the modem. Enter the AT prefix before all commands except A/ (Repeat Last Command) and +++ (Escape code). For more information about AT commands that begin with AT, see Table 1.
Usage guidelines
|
|
CAUTION: This command changes the modem operating state. Incorrect use of this command can cause issues such as dial-up failure. When you use this command, make sure you understand the impact of this command. |
To send AT commands to a modem, you must first place the modem in AT command mode. To confirm that you can send AT commands, enter sendat at. The modem will return OK or 0 if it is ready to accept AT commands.
One sendat command can issue one AT command. To send multiple AT commands to a modem, you must repeat the sendat command.
This command does not verify the validity of AT commands. To verify the AT command execution result, enable modem debugging on the interface. To view the AT commands sent to the modem, issue the E1 command to the modem.
Table 1 describes commonly used AT commands. Support for AT commands varies by modems.
Table 1 AT commands in common use
|
Command |
Description |
|
A |
Forces the modem to go off-hook in answer mode. If a call is coming in, the modem will try to answer it without waiting for the ringtone. This command is useful when manual answer mode is used. |
|
Bn |
Sets the modulation protocol preference. Available options: · B0—Selects the ITU V.22 mode. The transmission speed is 1200 bps. · B1—Selects the Bell 212 mode. The default transmission speed is 1200 bps. · B2/B3—Cancels the ITU V.23 backward channel. · B15—Selects the ITU V.21 mode. The transmission speed is 300 bps. · B16—Selects the 103J mode. The transmission speed is 300 bps. This setting is the default for Compaq Presario 192-VS and Compaq Presario 288-VS modems. |
|
Dn |
Dials a telephone number. The n argument represents the dial string. In pulse dialing mode, the modem ignores nonnumeric characters. |
|
En |
Controls echo of commands to the configuration terminal. Available options: · E0—Disables echo of commands to the configuration terminal. · E1—Enables echo of commands to the configuration terminal. This option is the default. |
|
Hn |
Sets the method to terminate a call. Available options: · H0—Forces modem on-hook to hang up the line (the default). · H1—Forces modem off-hook to answer or dial. |
|
In |
Displays modem information and results of checksum tests on firmware. Available options: · I0/I3—Displays the default transmission speed and controller firmware version. · I1—Runs a checksum on the ROM and displays the result. · I2—Runs a checksum on the ROM and displays the checksum status: ¡ OK—The checksum is correct. ¡ ERROR—The checksum is incorrect. · I4—Displays the hardware version of the data pump. · I5—Displays the product code, software version, hardware version, and country code. · I9—Displays the country code. |
|
Ln |
Sets the speaker loudness for fax and data communication. Available options: · L0/L1—Low volume. · L2—Medium volume (the default). · L3—High volume. |
|
Mn |
Sets the speaker mode for fax and data communication. Available options: · M0—Speaker is always off. · M1—Speaker is on until the carrier is detected. This option is the default. · M2—Speaker is on when the modem is off-hook. · M3—Speaker is on after a dial until the carrier is detected. |
|
Nn |
Sets the modulation negotiation mode for the modem to establish a connection with a remote modem operating at a different speed. Available options: · N0—Forces the modem to connect at the speed specified in the S37 register and the ATBn command. · N1—Enables the modem to start connecting at the speed specified in the S37 register and ATBn command. However, the speed may drop during the negotiation. This option is the default. |
|
On |
Forces the modem to return to data mode. Available options: · O0—Returns to data mode. · O1—Initiates an equalizer retrain sequence before returning to data mode. · O3—Negotiates the transmission speed before returning to data mode. After you use the +++ command to place the command in command mode, you can use an ATOn command to change the modem to data mode. |
|
Qn |
Enables or disables the modem to send result and status codes to the configuration terminal. Available options: · Q0—The modem sends result and status codes. This option is the default. · Q1—The modem does not send result and status codes. |
|
Sr=n |
Sets the contents of S register r to value n. · Value range for the r argument—0 to 27, 29, 31 to 33, 35, 37, and 89. · Value range for the n argument—0 to 255. |
|
T |
Sets tone dialing (the default). This command can also be used as a dialing modifier. |
|
P |
Sets pulse dialing. After you execute this command, the modem performs pulse dialing for all calls until you execute the T command. The P command can also be used as a dialing modifier. |
|
Vn |
Specifies the result code format. Available options: · V0—Sends numeric result codes. · V1—Sends text-form result codes (the default). |
