Modem Reference 6-19

\Kn Break Control

The AT\Kn command determines how the modem processes a Break signal received from the local DTE during a connection (online).

\K5 Modem sends Break to remote modem in sequence with transmitted data, non-destructive/non-expedited (default)

\Nn Error Mode Control Selection

The AT\Nn command sets the type of error correction supported by the modem when sending or receiving data.

\N0

Buffered mode. No error control (same as &Q6).

\N1

Buffered mode (same as \N0)

\N2

LAPM, MNP or disconnect mode. This is also known

 

as reliable mode.

\N3

LAPM, MNP, or buffered (default). The modem

 

attempts to connect in LAPM error control mode. If

 

this fails, the modem attempts to connect in MNP

 

mode. If this fails, the modem connects in buffered

 

mode and continues operation. This is also known as

 

V.42 auto-reliable mode (same as &Q5)

\N4

LAPM or disconnect. The modem attempts to connect

 

in LAPM error control mode. If this fails, the call will

 

be disconnected.

\N5

MNP or disconnect mode. The modem attempts to

 

connect using MNP 2-4 error control procedures. If

 

this fails, the modem disconnects. This is also known as

 

MNP reliable mode.

\Qn Local Flow Control Selection

The AT\Qn command sets the type of flow control used on the serial port to adjust for differences in modem port speed.

\Q0

Disables flow control (same as &K0)

\Q1

Sets flow control to XON/XOFF (same as &K4)

\Q3

RTS/CTS to DTE (default; same as &K3)

PRO/100 specifications

The Intel PRO/100 network adapter series, introduced in the mid-1990s, revolutionized networking by providing robust performance and reliability for both desktop and server environments. These adapters were pivotal in enabling fast Ethernet connectivity, helping to establish standards that would be instrumental in the advancement of network technology.

One of the primary features of the Intel PRO/100 series is its support for 10/100 Mbps Ethernet speeds. This dual-speed capability allowed organizations to transition seamlessly from older 10 Mbps networks to faster 100 Mbps connections without the need for a complete hardware overhaul. This adaptability made the PRO/100 cards a flexible choice for various network architectures.

Another significant characteristic of the Intel PRO/100 is its use of advanced bus mastering technology. This feature enhances data throughput by allowing the network adapter to take control of the system's bus when transmitting data. By doing so, it minimizes CPU overhead, which results in better overall system performance and efficient network communication. This was particularly beneficial in environments where network traffic was heavy, allowing the processors to handle other tasks without being bogged down.

The Intel PRO/100 series was also incorporated with Intel’s Plug and Play technology. This innovation simplified the installation process, automatically detecting the hardware and configuring it to work with existing system resources. As a result, system administrators could save time and reduce errors during setup, making it an attractive option for businesses looking to streamline their IT operations.

In terms of compatibility, the PRO/100 adapters supported a variety of network operating systems, including Windows NT, Linux, and Novell NetWare, providing users with a versatile solution for integrating into existing infrastructures. Furthermore, the cards were designed with high-quality, durable components to ensure longevity and reliability even in demanding environments.

Intel also emphasized the importance of network security and management with these adapters. The PRO/100 series featured capabilities for diagnostics and performance monitoring, allowing administrators to quickly identify and resolve network issues. Advanced features like Wake-on-LAN (WoL) provided additional functionality, enabling remote management and maintenance.

In conclusion, the Intel PRO/100 network adapter series represented a significant leap in networking technology during its time. With features such as dual-speed functionality, bus mastering, Plug and Play installation, and extensive compatibility, it laid the foundation for future innovations in network communication, solidifying Intel's reputation as a leader in networking solutions. Whether for small businesses or large enterprises, the PRO/100 series offered the reliability and performance critical to maintaining efficient and effective network operations.
