INSTRUCTIONS FOR SERIAL PORT PROTOCOL ===================================== This folder contains the base code of the serial port protocol. Project Structure ----------------- - bin/: Compiled binaries. - src/: Source code for the implementation of the link-layer and application layer protocols. Students should edit these files to implement the project. - include/: Header files of the link-layer and application layer protocols. These files must not be changed. - cable/: Virtual cable program to help test the serial port. This file must not be changed. - main.c: Main file. This file must not be changed. - Makefile: Makefile to build the project and run the application. - penguin.gif: Example file to be sent through the serial port. Instructions to Run the Project ------------------------------- 1. Edit the source code in the src/ directory. 2. Compile the application and the virtual cable program using the provided Makefile. 3. Run the virtual cable program (either by running the executable manually or using the Makefile target): $ ./bin/cable_app $ make run_cable 4. Test the protocol without cable disconnections and noise 4.1 Run the receiver (either by running the executable manually or using the Makefile target): $ ./bin/main /dev/ttyS11 rx penguin-received.gif $ make run_tx 4.2 Run the transmitter (either by running the executable manually or using the Makefile target): $ ./bin/main /dev/ttyS10 tx penguin.gif $ make run_rx 4.3 Check if the file received matches the file sent, using the diff Linux command or using the Makefile target: $ diff -s penguin.gif penguin-received.gif $ make check_files 5. Test the protocol with cable disconnections and noise 5.1. Run receiver and transmitter again 5.2. Quickly move to the cable program console and press 0 for unplugging the cable, 2 to add noise, and 1 to normal 5.3. Check if the file received matches the file sent, even with cable disconnections or with noise
