2.7 Testing Your Modem After Installation

In order to test your modem you should be familiar with your communication software. Load and set up your communication software and enter into “terminal mode.” Make sure that the COM Port and IRQ settings of the modem match the software. Type AT on your terminal screen and press ENTER. You may see “AT”, “AATT” or nothing on the screen. In any case, the modem should respond with an OK or 0. If it does not, either the modem may not have been installed properly or the software has not been properly configured. Review Sections 2.2-2.5 and be certain that the modem and the software have been properly installed. If required, refer to Section 6 for additional troubleshooting information.

2.8 Using Your Modem

The communication software included with your modem product provides a user friendly interface to access the fax, voice and data functions of your modem.

This software should be sufficient for all of your communication needs. There may be times when you need to access the modem manually via modem com- mands. Read Section 3 for a summary description of the modem command set before manually accessing the modem. You may want to read the software manual first, however, as the software may already provide a user friendly method of accessing the functions you need (i.e. dialing or answering calls).

2.9 Where To Go From Here

You should familiarize yourself with the functions availablefromtheincludedsoftwarebyreadingitsmanual. You will be accessing most, if not all, of the modem's functions from this software. You may also use any other commercially available communication software with the modem. Read Section 3 ONLY if you are interested in accessing the modem manually, and not through the included software. Section 4 and 5 contain reference material, and can be skipped. If you have difficulties getting your modem to work, read Section 6 - Trouble- shooting to find answers to commonly asked questions and problems.
