who to exit minicom connected to Raspi

I have a Raspberry Pi with a Rio Board attached. When I go into the minicom from the command prompt minicom does not seem to work. I can't even get the Help file to come up. The biggest problem is, i can not Escape or Exit the program without turning off the power. This seems to corrupt the SD card to the extent that Raspi and Rio seem to work (4HZ flashing light) but no video out. I can't find any information on minicom or specifically how to exit it and test it to make sure it works.

Does anyone have a solution?

There needs to be a Topic for the RIO and Raspberry pi on this Form because some of these issuers seem to be specific to them.

I am sure you know that already, but just to be sure we are doing the same and to quickly figure out your problem. In order to start "minicom" with correct serial port device selected and settings provided please run:

In order to end "minicom" session try pressing:

May I ask how did you intend to test "minicom"?

I was trying to get it to respond to anything to demonstrate any functionality. I am basically trying to learn some of the communication protocols.

Where are the commands you refer to referenced?

if minicom is "off line" can the Help files be accessed?

I am not sure I completely understand your setup. Please describe what exactly are you trying to achieve and what is your arrangement (how is the RaspberryPi connected to PC, for example).

I would expect one of the following:
- You have monitor connected over HDMI (or TV connected with S-Video), with the keyboard - over USB
- You have Ethernet/WiFi connection and access your board over SSH (for example with Putty)
- You connect to RaspberryPi over serial port, directly to PC or via USB/Serial adapter, and use for that Serial port terminal software like Hyper Terminal, Putty (in Serial port mode), minicom or software alike

thanks, I now understand minicom and it's use. moving on to the serial interface.
