The server must follow the next especifications.

* Command line --> ./LinuxServer -port xxxx (The server have to run the port indicated in the command line)

* The server have to start and remain in the "listening conexions" state.

* When a conexión come form a client with a "START" frame, the server have to move to "transfer" state.

* The first frames that the server have to send to the client are information frames, one or two.

* for every frame send it to the client have to wait for ACK or NACK frame.

* Once the client notify to the server that have receive the information frames (in one of this go information related to a file)

* The server have to read a *.hex file line by line and send it to the client.

* If there is a NACK the server have to retransmit the las frame send it.
