Zoom USB Faxmodem quick start Initialization Strings, Command Sets

Tips for Selecting Setup Options

In setting up some older software programs, you may be asked to enter certain information. Most programs have default settings that are correct for use with this modem, and there is no need to change them. Nevertheless, you should be aware of the following items:

•If you are asked to select the “modem type” from a menu, and you don’t see this modem listed by name on the menu (for instance, Zoom External V.90 56K USB Faxmodem), select the most descriptive name such as V.90 modem, 56K modem, or generic Class 1 fax modem.

•If you have a PC, in the dialing directory set all entries to the highest possible baud rate, if your software sup- ports these speeds (do not go over 115,200). All com- munications between the computer and the modem take place at this higher speed, independent of the modem-to-modem speed.

•If your fax software gives you the option of selecting Class 1 or Class 2 fax drivers, select Class 1.

Initialization Strings

An initialization string is a group of AT command settings that the software sends to the faxmodem to initialize it. Your software determines which commands should be in- cluded in the initialization string, based on the modem you select during software installation.

Your software may send other AT commands to perform actions such as dialing a phone number or answering a call. This is transparent to you—the software does this in the background without your having to be aware of it.

It is sometimes necessary, however, to add other AT com- mands to initialization strings. You can find a description of AT commands on the World Wide Web at www.modems.com. Click on Reference and then on AT
