trying to use teh sample program

[otalado]

I have a straightforward scenario: I send a command (string) to the device on the serial port, and if the command is correctly formatted, the device executes the command and responds with a string. Using the sample program, I see that the device gets the command (it executes it correctly), but the program never shows a response from it. When I try the same thing with the TeraTerm utility, I am getting an expected response from the device, so obviously, I should change something in the program. Unfortunately, my knowledge is inadequate to fix the issue. Help would be appreciated.
