15.2 Command Echo Problems
Problem
You do not see any typed characters on your computer screen.
Solutions
1. Make sure the DTR LED is ON. If it is OFF, make sure your communications
software is using the same COM port as your modem.
2. Neither your modem nor your communications software is configured to echo
characters. Use the E1 command to enable modem echo, or turn on your
software program's Echo (or duplex) feature.
Problem
Each character you type appears twice on your computer screen.
Solution
Both your modem and your communications software are echoing characters to your
screen. Use the E0 command to disable modem echo, or turn off your software program's
echo (or duplex) feature.
15.3 Auto-Answer Problems
Problem
Your modem does not auto-answer incoming calls.
