Hi,

I am running an Open suse 10.2 in my system...and my minicom version is 2.2..

i am connecting my serial port to my targets serial port..

As soon my target is booted, i can see the bootup text messages on my minicom screen...But what ever i type on the minicom screen, i could not get it on the screen..

I tried Local echo ON, then some how i could get what i typed on the screen, but my board is not responding to my input...the same board works well with the minicom 2.0 installed on an Red Hat enterprise Linux..

All the setting and baud rate are Ok...

Is there any tweaking i should do to make it work??

Have you ruled out a hardware failure on the SUSE system? If the TX lines were damaged, then you would only be able to see the output from the device and not send anything to it.

It could also be a permissions issue, where you have read but not write permissions to /dev/ttyS0. You may want to try running minicom as root to see if that fixes the issue (if you have not already). If it works under the root account, then you need to modify the permissions on the device, or put your user into the appropriate group(s).

Hi...

thanks for your reply...

My serial cable is working properly...This i checked by connecting my target board through the same serial cable to another computer,where the minicom is working properly... so serial cable is not faulty...

I tried starting the minicom as root...then also the problem is persists...

what else may be the issue??

What MS3FGX said might apply to the serial port hardware itself as well. Make a connector with pins 2 and 3 shorted as a test device and connect that to the serial port of the PC.
Start minicom and type something, it should echo what is transmitted (if local echo is on, you should see it twice).
