I am developing an RFID-based timing system for timing cycling races. Currently have an application which was written for manual entry of race numbers using the keyboard. The RFID reader passes hex data to the PC through a serial or TCP port. I need to convert the received data into meaningful race numbers and then transmit these numbers to the app as keystrokes. i.e 0004, or 0005, etc. followed by a comma and "ENTER"
The problem...

I am looking to develop an interface to monitor traffic on a computer's USB/Serial ports.

How would I accomplish this?

I am just simply looking for a method on how to do it, the rest I can take care of.

Thanks in advance.

Hello,

I need to write a script to listen to a serial port basically forever. The python script will be launched by another program and the input to the com port passed to the other program. As long as this other program is running, I need the python script to run and handle the com port traffic.

I have this working (thats about it),

Code:

import serial
from scala5 import sharedvars
import

Hello everyone

How can I communicate with USB drive using C code?

Like in ethernet, we have source ip address, destination ip address for communication between source and destination. How can I do this in USB? What parameters do I need to set in USB for communication.

Any help would be appreciated.

I wrote a C program that is successfully able to read and write from the serial port.
When the program is run in shell or terminal on linux it can read and write data to the micro controller.
However when the program is embedded in PHP <?php echo exec("./send toserial.out"); ?> it is unable to send information to the micro controller.
I have tried other programs embedded in PHP, like a C program that can read and...
