Not able to read data through serial port

Question

Dear all,

I am to read data on serial port.

My setup OS: Ubuntu linux

Device 1: BeagleBoard Device 2: My laptop

I am using a serial to usb converter.

Serial device on BeagleBoard: ttyS2

Serial device on Laptop : ttyUSB0

I did a simple thing to test the connection, I ran minicom on both the machines. when I type something on BeagleBoard I receive data on laptop but it doesn't work the opposite way. What can be the reason.

The setting for serial port on both the devices are

Baud rate: 115200

Data size: 8 Parity:N stop bit:1

Hardware flow control : no

What can be the reason

Cheers !!! Chaitannya
