Modem Initialization Strings

Technical Support Resources for First Internet Franchise Corp
Last updated on March 13th, 1996


What is a modem initialization string?

    A modem initialization string is used by the software in your computer to properly prepare your modem to dial, and later, connect.

    If the proper modem string is not being used, your modem will show poor performance, will have low connection rate consistency, and may not even dial at all!

    Some modems will work fine without a modem initialization string present in the login script, though most will not. Sometimes, a default string, usually "ATZ" or "AT&F" will suffice.


Search for your modem using the first letter of the Manufacturer's name..
