    2. Also, MS Messenger use to greet me...now I am receiving no greeting..is there some box that needs to be checked/unchecked

    3. How do you go about changing between half duplex and full duplex on a modem

    Any assistance appreciated

    1. How do you expand Add/Remove Programs under Control Panel to show all programs such as Internet Explorer, etc

    You cannot beyond clicking Add/Remove Windows Components, only shows a few items. Many Windows components such as Internet Explorer and Media Player are built-in to the OS, therefore, cannot be removed, which is why the governemnt is after Microsoft .

    2. Also, MS Messenger use to greet me...now I am receiving no greeting..is there some box that needs to be checked/unchecked

    MS Messenger can be removed using Add/Remove Windows Components. I would try installing it, reboot, and reinstall it.

    3. How do you go about changing between half duplex and full duplex on a modem

    It usually controlled by the protocol being used. TCP-IP is Full Duplex only. If you using a Async terminal emulator, such as HyperTerminal, it's controlled by the application.

    Here some infor to explain half duplex:

    It refers to the transmission of data in just one direction at a time. For example, a walkie-talkie is a half-duplex device because only one party can talk at a time. In contrast, a telephone is a full-duplex device because both parties can talk simultaneously.

    Most modems contain a switch that lets you select between half-duplex and full-duplex modes. The correct choice depends on which program you are using to transmit data through the modem.

    In half-duplex mode, each character transmitted is immediately displayed on your screen. (For this reason, it is sometimes called local echo -- characters are echoed by the local device). In full-duplex mode, transmitted data is not displayed on your monitor until it has been received and returned (remotely echoed) by the other device. If you are running a communications program and every character appears twice, it probably means that your modem is in half-duplex mode when it should be in full-duplex mode, and every character is being both locally and remotely echoed.
