\Tn Inactivity Timer Limit

The AT\Tn command specifies length of time (in minutes) that the modem waits before disconnecting when no data is sent or received. The time period can be set at n = 0 - 255. A setting of zero disables the timer. As an alternative, the timer may be specified in S-Register S30. This function is only applicable in buffer mode.

\Xn XON/XOFF Pass Through

\X0 Modem process XON/XOFF flow control characters locally (default)

\X1 Not supported; returns ERROR

%B View Numbers in Blacklist

If blacklisting is in effect, the AT%B command displays the numbers for which the last call attempted in the past two hours failed. In countries that do not require blacklisting, this command returns ERROR.

%Cn Data Compression Control

The AT%Cn command determines the operation of V.42bis and MNP class 5 data compression. Online changes do not take effect until a disconnect occurs.

%C0

V.42bis/MNP Class 5 compression disabled (no data

 

compression)

%C1

MNP Class 5 compression enabled (no V.42bis)

%C2

V.42bis compression enabled (no MNP Class 5)

%C3

V.42bis/MNP Class 5 data compression enabled

 

(default)

-Cn Data Calling Tone

Data calling tone is a tone of a certain frequency and cadence specified in V.25 that allows remotes data/fax/voice discrimination. The frequency is 1300 Hz with a cadence of 0.5 seconds on and 2 seconds off.

-C0

Disables calling tone (default)

-C1

Enables calling tone

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.
