I am using a verdex XL6P and console-hw. I use ttyS3 (which I believe is the
second serial port on the console-hw) to comunicate with a c# program
running on a laptop through a c++ program running on the gumstix. I used
fstream for writing to and reading from the serial port. when I run the
program it keeps running even when there is no data sent from the laptop and
the values that are received are always just "". could some one please help.
