I installed minicom and configured it with a usb to serial adapter. When I run minicom with sudo minicom I see only this message : Welcome to minicom 2.7

OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19. Port /dev/ttyUSB0, 10:07:54

Press CTRL-A Z for help on special keys

I should see a Cisco ios. What I can do ?

It seems you cannot input anything on minicom, if that is the case then go in Minicom configuration by:

minicom -o -s

and select the serial port setup option, then turn off the Hardware flow control. I also had software flow control to OFF. It works for me.

May be you can try to use picocom like this:

sudo picocom -b 115200 -r -l /dev/ttyUSB0

with no port reset (-r) and no port locking (-l). Also special keys you can see in the man picocom

I resolved. If I use picocom with your command doesn't work because the bitrate 115200 is wrong. If I launch picocom with 

sudo picocom -l /dev/ttyUSB0

it works fine.

therefore if I change the bitrate in minicom also. It work fine.

finally I relsoved. Thanks so much

Maybe it's device.

Look for ACM*:

ls /dev/ttyACM*

If you get - for example /dev/ttyACM0 - then start minicom with it.

minicom -b 38400 -D /dev/ttyACM0

I had this issue with an HC-05 bluetooth module.

You should just press enter. When you start minicom, the login prompt was already issued on terminal and is not displayed again.
If nothing helps make sure you have proper flow settings (in port configuration). For emulation connections like via USB or Ethernet you usually should have both off. Check speed too.
