    Additional Modem Information Data Compression Most high-speed modems also try to negotiate a compression protocol such as v.42 bis or MNP5 upon establishing a connection to another modem. Compression settings do not effect the ability to connect to IRC. However, negotiating such a protocol is advantageous, since it greatly accelerates responses from the server, particularly in remote console mode.

    Modem Sharing Asynchronous Management Asynchronous Management is a Compaq software option that allows you to monitor server health and receive traps through an asynchronous (modem) connection. This feature is essential to properly manage remote servers that may not be connected through a local area network. For servers with a LAN connection, this feature provides an important backup communication path in instances when the network is down.

    Graphical Remote Control The modem sharing feature of IRC can also be used to obtain graphical remote control through OS-based applications such as pcANYWHERE or Compaq Carbon Copy. Typically, these programs support several communication methods, including several network transports as well as direct modem access.

    Modem Sharing Additional Information Determining Proper Initialization Strings in a Windows NT 4.0 RAS Environment Each modem supported under Windows NT is uniquely described by an entry in a modem information file (*.INF). This file, which is either provided by Microsoft as part of the Windows NT installation or provided by the modem vendor, contains specific configuration information necessary for Windows NT applications to fully utilize the modem.
  • Page 108 Temporarily disable IRC If IRC is enabled, temporarily disable IRC using the Compaq System Configuration Utility. This prevents incorrect settings from interfering with RAS. Turn on Modem Log File 1. From the Windows Control Panel, double-click on Modems. 2. From the Modem Properties dialog box, select the modem that you want to share with IRC and click Properties.
