6-28PRO/100 LAN+Modem PC Card User’s Guide

S8 Duration of Pause for Comma Dial Modi- fier

This register determines the number of seconds to pause for each comma (,) in a dial string or command line. The default is 2 seconds, but any value from zero to 65 is acceptable. Defaults and limits are country-specific.

S10 Delay Between Lost Carrier/Hang Up

This register specifies the time (in tenths of a second) that the modem waits after carrier loss before hanging up. The default is 20 (2.0 seconds). This allows for temporary carrier loss without causing the local modem to disconnect. Register S10 will accept a value ranging from 1 to 254 in tenths of a second (0.1 to 25.4 seconds). Defaults and limits are country-specific.

S11 DTMF Tone Duration

This register determines the “touch tone” dialing speed which is prefixed for each country. The value can range from 50 to 150 milliseconds. The default is 95 milliseconds. The value of register S11 has no effect on pulse dialing. Defaults and limits are country- specific.

S12 Escape Guard Time

This register sets the value (in 20 ms increments) of the required pause after the escape sequence. Range is 0 = 255, default is 50 units of 0.02 seconds each, or one second.

S28 V.34 Modulation Enable/Disable

This register enables or disables V.34 modulation. Default setting is 1, valid values are 0 or 1. A value of zero disables V.34 modulation. Any other value in the range enables it.

S30 Inactivity Timer

The value specified by this register sets how long the modem will wait (in minutes) before disconnecting when no data is sent or received. This function is only applicable in buffer mode. It is set

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.
