COM Port is not Working

KrishnaPavan — Tue, 01 Nov 2011 09:29:26 GMT

COM Port is not working when I connect my board in this way

I am using minicom, all the necessary drivers have been installed.

When I use Serial Cable I connect with minicom configured like this

When I use USB i use Serial Device as /dev/ttyUSB0 .

When I use a USB to Serial Connector, the board is then working fine, I mean I am able to communicate with my board.

The serial cable and COM Port if used individually are working fine.

Any idea about this problem?

I am not able to type, which means that the transmission has got problem...

The loop back test using gtkterm/minicom did not give me any result.

Is there an error within the board or is the error with my PC?

Hi,

As early mentioned I have been checking the DB9 connector.

Even the statserial software could show the same.

Which means that the COM Port is not receiving any data that is transmitted to it.

Here are the pics of the Stat Serial

I just connected the board, Now the booting sequence has been initiated after Power Up

Now I need to enter the log-in that is by default root

Now that stats are

Any Infererences?

Have any one faced the problem with the COM Ports on the board/PC. Regards :: Krishna Pavan
