WFWG RAS: Optional Modifiers and Dialing Strings

• Microsoft Windows for Workgroups version 3.11

SUMMARY

The following information explains the dialing modifiers used in the Microsoft Windows for Workgroups Remote Access Services (RAS) client.

MORE INFORMATION

Touch-Tone Dialing and Pulse/Rotary Dialing

By default, Windows for Workgroups RAS uses your current telephone system format for dialing (either touch-tone or pulse/rotary dialing). It may be necessary to use touch-tone only, pulse/rotary only, or both to get an outside line on some telephone systems.

Use the following information to switch between dialing scripts when you enter numbers to dial:

• The letter "T" switches from pulse/rotary to touch-tone dialing.

  Example: If you are dialing from a telephone system that supports pulse/rotary dialing and you need to enter a touch-tone format for a calling card, the dial string is 555-5678T1234. Every digit after the "T" is in touch-tone format.

• The letter "P" switches from touch-tone to pulse/rotary dialing.

  Example: If you are dialing from a telephone system that supports touch-tone dialing but it is connected to the telephone company through pulse/rotary dialing, the dial string is 123P555-5678. The "123" prefix tones may be used to access specific in-house functions or access specific telephone lines. Every digit after the "P" is in pulse/rotary format.

• You can use the "T" and "P" switches together to switch between formats.

  Example: 555-1234P123T456 (tone-pulse-tone)

Telephone Number Modifiers for RAS

The following telephone-number modifiers are used to help get an outside line on some telephone systems.

• The comma (,) causes the dialing to pause briefly (two seconds for most modems) before continuing.

        Example: 9,555-1234. The "9" is used on some telephone systems to get
        an outside line. The comma inserts a pause before dialing the
        telephone number. You can use as many commas as needed to create a
        longer pause before the telephone number is dialed.
  

• The at sign (@) waits for extended silence before continuing. This symbol causes the modem to listen to silence for five seconds. If a five-second silence has not been detected within the period predefined in the BIOS S7 register of the modem (the default is 50 seconds), the modem disconnects. If five seconds of silence are detected, the modem continues dialing the dial string.

        Example: 9@555-1212
  

• The letter "W" waits for a dial tone before continuing (for modems operating at 2400 bits per second [BPS] or greater). This dial modifier causes the modem to wait for an additional dial tone before dialing the numbers that follow the "W." The length of time the modem waits is up to the value in the BIOS S7 register of the modem (the default is 50 seconds). The modem can be instructed to dial through a private branch exchange (PBX) or a long-distance calling service that requires delays during dialing.

        Example: 9W555-1212. The "9" accesses the outside (public) telephone
        line. The "W" causes the modem to wait 50 seconds for a secondary
        dial tone (unless the default value in the BIOS S7 register of the
        modem has been changed). Then the 555-1212 telephone number is
        dialed.
