Hi,

I have a PC, to which a development board is connected via USB. To the board, a DUT is connected via USB again.

So, PC ------USB1--------> DevBoard -----(USB2)------> DUT

USB1 is /dev/ttyUSB0 (in the PC)
USB2 is /dev/ttyUSB2 (in the board)

If I need to pass AT commands from PC to DUT, can I use socat? If yes, please share some inputs on how the command would look like.

Thanks and regards,
Sai.

Hi Siam - and welcome to the Forum.

First thing:   Please put your posts on appropriate Board - we had to move it here.  Indeed, if you had read the New Members' Guide (where you posted) you would know what to do.

I have no experience of socat but a web search seems to indicate that you can't get all the way from a PC command through your Development Board to your DUT. 
But you might be able to get socat to create a file on your DB that you could read via s/w you write for the DB.  Just a thought.

There are tutorials on the web that might help you.
