&Wn

Store Current Configuration

This command stores certain command options and S-register values except S3, S4, and S5. The ATZ command or a power-up reset of the modem restores this profile.

Result Codes:

OK ERROR

&YnSelect Stored Profile for Hard Reset

This command does not change the behavior of the modem but is included for compatibility with applications that

issue the &Y0 command

&Y0:

Select stored profile 0 on power-up

&Y1:

ERROR

Result Codes:

 

 

OK

 

n = 0

ERROR

Otherwise

&Zn=x

Store Telephone Number

This command is used to store up to four dialing strings for later dialing. The format for the command is &Zn = ”stored number” where n is the location 0—3 to which the number should be written. The dial string may contain up to 40 characters. The ATDS = n command dials using the string stored in location n.

Result Codes:

OK

 

n = 0, 1, 2, 3

ERROR

Otherwise

\An

Select Maximum MNP Block Size

The modem will operate an MNP error corrected link using a maximum block size controlled by the parameter supplied.

 

\A0:

64 characters.

 

\A1:

128 characters.

 

\A2:

192 characters.

 

\A3:

256 characters (default).

Result Codes:

 

 

OK

n = 0, 1, 2, 3

 

ERROR

Otherwise

\Bn

Transmit Break to Remote

In non-error-control mode, the modem will transmit a break signal to the remote modem with a length in multiples of 100ms according to parameter specified. The command works in conjunction with the \K command.

\B1 - \B9:

Break length in 100ms units. (Default = 3.) (Non-error-control mode only.)

Result Codes:

 

OK

If connected in data modem mode.

NO CARRIER

If not connected or connected in fax modem mode.

\G

Modem Port Flow Control

 

 

\G0:

Modem process XON/XOFF flow control characters locally (default).

 

\G1:

Modem passes XON/XOFF flow control characters.

 

Result Codes:

 

 

 

OK

n = 0, 1

 

 

ERROR

Otherwise

Host-Based Controller Modem AT specifications

Lucent Technologies Host-Based Controller Modem AT represents a significant advancement in modem technology, particularly in the realm of telecommunications and data transmission. This modem, renowned for its efficiency and versatility, is characterized by a host-based architecture, which differentiates it from traditional modems that rely heavily on dedicated hardware.

One of the main features of the Lucent Technologies Host-Based Controller Modem AT is its ability to leverage the processing power of the host computer. By utilizing the host's CPU for data encoding and decoding tasks, the modem can reduce the need for specialized hardware components, allowing for a more cost-effective solution. This design not only facilitates lower manufacturing costs but also enhances the overall performance due to the utilization of the host's computational capabilities.

Another notable characteristic is its compliance with the AT command set, which standardizes communications between the modem and the host system. This ensures compatibility with a wide range of software applications and operating systems. The AT command set allows users to control modem functions easily, making it simpler to configure settings, initiate connections, and manage data transfer processes.

The modem also supports various communication protocols, such as V.90 and V.92, enabling high-speed data transmission over traditional telephone lines. With download speeds of up to 56 Kbps and upload speeds of up to 48 Kbps, the Lucent Technologies Host-Based Controller Modem AT is particularly suitable for Internet browsing, email, and other online activities demanding robust data throughput.

Additionally, the modem features built-in error correction and data compression protocols, such as V.42 and V.44, further enhancing the quality and speed of data transmission. These protocols help minimize the impact of line noise and ensure efficient use of bandwidth, leading to improved connection stability and data integrity.

In terms of connectivity, the Lucent Technologies Host-Based Controller Modem AT typically interfaces via a standard serial or USB port, making it compatible with most modern computers. Its compact design and ease of installation make it an appealing choice for both personal and professional use.

Overall, the Lucent Technologies Host-Based Controller Modem AT showcases significant innovation in modem technology, offering users a reliable and efficient solution for high-speed data communications. Its host-based architecture, adherence to the AT command set, and support for advanced communication protocols position it as a vital tool in the ever-evolving landscape of digital connectivity.
