I can connect to serial port in /dev/ttyUSB0 using screen or minicom. When I type the AT commands, the letters I type do not appear, just the output message. Example: If a type "AT" and press enter, the "AT" doest not appear, but the "OK" output message appear normally. What's wrong?

Press Ctrl+A, then E.

This way minicom will echo the typed symbols on screen.

You can enable echo in device itself, if it supports it by

ATE

command.
