Page 17: General Troubleshooting
For help with this problem… The modem disconnects while communicating with a remote system. The modem does not make a data connection. You receive bursts of errors occasionally, but otherwise data quality is good. Random errors occur in transmitted data. Data is missing. - Page 18 Problem: You type an AT command line and press En- ter, but your modem fails to execute the command line. Solution: Be sure you type AT at the beginning of the command line. Make sure the communications software is configured for the same serial port as your mo- dem.
- Page 19 Problem: Modem does not auto-answer. Solution: Your modem may not be configured to auto- matically answer incoming calls. If you want your fax or data software to answer calls, be sure you have selected this option in your soft- ware. Problem: You encounter other communications prob- lems with your modem.

Page 20: Echo Troubleshooting
Type: AT &C0 &W &Y0 and press Enter. Also make sure that the faxmodem initializa- tion string does not include &C1. If your software requires that Data Carrier De- tect follow carrier, the above considerations apply in reverse. If you are having problems, include &C1 in the faxmodem initialization string. -
Page 21: Dial Troubleshooting
Dial Troubleshooting Problem: The modem does not automatically dial a call when you send a Dial command. Solution: Make sure the modem speaker is turned on in your software so that you can hear dialing sounds. Also make sure that the telephone line is plugged in. - Page 22 Note 1: The first two lines in the table are likely to be the most valuable. Note 2: In the command strings shown in the table that follows, the character after “N” is zero, not the letter “O.” Note 3: Some commands vary because of the processor used in the faxmodem.
- Page 23 Note 4: You may find it necessary or helpful to include W2 in your initialization string or dialing prefix. This enables responses that include the mo- dem-to-modem speed. Note 5: Some software allows these commands to be added to the list of dial prefixes or the initiali- zation string.
- Page 24 “Normal” operation (The faxmodem commu- nicates without any error correction or data compression, but retains speed buffering and auto-speed negotiation. It should not be confused with the “standard” configuration.) Auto-answer Problem: Your online service reports a connect speed that doesn’t match your modem’s speed. Solution: To get your online service software to report the actual connect speed, add W2 to the end of the initialization string, or to the dial prefix, just...
- Page 25 Problem: Your modem does not make a connection. Solution: If your modem places telephone calls but never makes a connection, make sure you are dialing the right number. The remote modem may be turned off. Problem: You receive bursts of errors occasionally, but otherwise data quality is good.
- Page 26 Problem: Your faxmodem is not communicating data as fast as you expect. Solution: For data communication above 14,400 bps, make sure that the modem at the other end of the telephone connection also supports V.34. Follow the recommendation provided under Tips for Selecting Setup Options in Chapter 2 for setting the port speed in the software.
